What happens when a charged balloon is placed near a stream of water?

What happens when a charged balloon is placed near a stream of water?

When you bring the negatively charged balloon close to the stream of water, the hydrogen end is attracted towards the balloon and the oxygen end is repelled away from it. This pair of forces twists the water molecule so that the line from the negative pole to the positive pole points towards the balloon.

Why does a rubbed inflated balloon when brought near your arm but not touching it causes the hairs on your arm to raise?

This is because the rubbing creates a negative charge that is carried by electrons. Consequently, when you pull the balloon slowly away from your head, you can see these two opposite static charges attracting one another and making your hair stand up.

Why did the water attracted to the charged comb or balloon?

Because the molecules in the stream can be moved easily, the stream bends toward the comb. On the right side, the water stream is attracted towards the positively charged comb. The molecules orientate their dipoles, the negative oxygen towards the comb; the positively charged hydrogens away from it.

Why is the balloon attracted to the wall if it’s close by but repelled when far away?

What happens when the balloon is close to, but not touching the wall? The electrons in the wall repel because of the negatively charged balloon, exposing the positively charged nucleus, allowing the balloon and wall to attract each other. (Electrons repel to the back of the wall).

What happens when a charged balloon is brought close to a wall?

When the charged balloon is brought near the wall, it repels some of the negatively charged electrons in that part of the wall (negative charges repel other negative charges, and positive charges repel other positive charges). Therefore, that part of the wall is left repelled.

Does a balloon have a positive or negative charge?

When you rub a balloon on a sweater, for example, some electrons come off and end up on the balloon. The fibers have lost electrons giving them a positive charge. Since electrons have a negative charge, the balloon now has a negative charge.

What charge does a balloon have after rubbing on hair?

When you rub a balloon on your head, electrons move from the atoms and molecules in your hair onto the balloon. Electrons have a negative charge, so the balloon becomes negatively charged, and your hair is left with a positive charge.

Why would a balloon attract your hair without touching it?

Hold the balloon (negatively charged) just above your head so your hair (positively charged) will be attracted to it and stand up on end. The can will start to roll towards the balloon without touching it. The negatively charged balloon repels the electrons of the can so that a positive charge is near the balloon.

What happen when you bring the balloon near your hair after rubbing it?

Rubbing the balloon onto your hair or onto the wool fabric adds electrons to the balloon and causes the balloon to become negatively charged. Your positively charged hair is attracted to the negatively charged balloon and starts to rise up to meet it.

What happens when you rub a balloon with a cloth?

When rubbing a balloon with a wool cloth, it puts negative charges on the balloon. Negative charges attract to positive charges. When both balloons are rubbed with the wool cloth, the both receive negative charges, so they will repel each other.

When you walk across a carpet electrons rub off the carpet onto your shoes when this happens which becomes negatively charged the carpet or your shoes?

Therefore, when you walk across a wool carpet in rubber-soled shoes, electrons transfer from the carpet to your shoes. You become negatively charged, while the carpet becomes positively charged. Another example of conduction is pictured in Figure below.

What happens when two charged balloons are brought close together?

In contrast to the attractive force between two objects with opposite charges, two objects that are of like charge will repel each other. That is, a positively charged object will exert a repulsive force upon a second positively charged object. This repulsive force will push the two objects apart.

What happens when a charged balloon is rubbed with a damp hand?

5. When you are finished, you can bring the balloon back to neutral by rubbing it with a damp cloth. Moisture in the cloth gives the negative charges (electrons) a path back to ground, and there is no longer a build up of negative charges on the balloon.

What happens when two positively charged hairs are next to each other?

Positive charges repel each other, so your charged hairs repel each other and stand out from your head.

Is it possible that two like charges attract each other?

Yes, when the charge on one body (q1) is much greater than that on the other (q2) and they are close enough to each other so that force of attraction between q1 and induced charge on the other exceeds the force of repulsion between q1andq2.

What happens when two negative charges come together?

According to Coulomb, the electric force for charges at rest has the following properties: Like charges repel each other; unlike charges attract. Thus, two negative charges repel one another, while a positive charge attracts a negative charge. The attraction or repulsion acts along the line between the two charges.

Can two like charged balls attract each other if yes why?

Answer: they can attract each other when one of them is very very large than the other then the electrostatic force acting on the two is not due to their initial charges but will be due to the charges produced due to induction. and hence attraction takes place.

What if like charges attract?

When it comes to electric charge, there is one overriding theme: opposites attract, and like charges repel. As far back as 1980, research has shown that like-charged particles can attract one another when placed in an electrolyte solution containing multivalent counterions.

How does a material become positively charged?

An electrical charge is created when electrons are transferred to or removed from an object. Because electrons have a negative charge, when they are added to an object, it becomes negatively charged. When electrons are removed from an object, it becomes positively charged.

Why do neutral and charged objects attract?

Neutral object are attracted to either charge. The region that has too many electrons is negatively charged, the other region positively, because of lack of electrons. The positive region since it is closer to the charge will be attracted to this charge. This process is called induction.

Can a charged body attract another charged body?

Yes, a charged body attracts an uncharged body as the oppositely charged bodies attract each other. This is known as the force of attraction.

What happens if a charged body is brought near to uncharged body?

When a charged body is brought near an uncharged body, an opposite charge is developed on the uncharged body near the charged body. This is called induction. The charges on the charged body do not lose by the method of induction. In fact, the free electron of uncharged body accumulates near the charged body.

Why does a charged body attract an uncharged body?

Yes, a charged body can attract another uncharged body. When the charged body is placed near the uncharged body, the induced charges of opposite kind are produced on the uncharged body by the charged body. Now, they are oppositely charged and the uncharged body is attracted by charged body.

Why does a charged body lose its charge when touched?

When we touch a charged body, it loses its charge, due to the process of earthing. It transfers the charges to the earth.

Why do charged objects lose their charge when touched Class 7?

Human body is a conductor of electricity. So, when we touch a charged object, our body conducts its charges to the Earth. That is why a charged body loses its charge, if we touch it with our hand. This phenomenon is known as earthing.

Which of the following Cannot be charged easily?

Copper rod cannot be charged easily by friction because it is a conductor. Only non-conducting materials can be charged easily by friction.

Why do objects lose their charge?

When an object gains electrons, it has a surplus of electrons and is said to have a negative charge. When an object loses electrons, it has a shortage of electrons, it has a shortage of electrons and is said to have a positive charge.

When an object is positively charged it has more?

Positively charged objects have electrons; they simply possess more protons than electrons.
