Polarization of Charge

What happens to the balloon when it is rubbed against fur?

• It loses electrons and becomes positively charged.

• It gains electrons and becomes negatively charged.

• It remains neutral.

• It gains protons and becomes positively charged.

Why does the balloon stick to the whiteboard?

• Because of conduction.

• Because of induction.

• Because of polarization.

• Because of gravitational force.

According to Coulomb's law, what happens when the distance between two charges decreases?

• The electric force increases.

• The electric force becomes zero.

• The electric force remains the same.

• The electric force decreases.

How does a negatively charged balloon affect small pieces of paper?

• It polarizes the paper, causing attraction.

• It has no effect on the paper.

• It charges the paper by conduction.

• It repels the paper due to like charges.

What happens to the electrons in an aluminum can when a charged balloon is nearby?

• They leave the can entirely.

• They remain evenly distributed.

• They move to the opposite side of the can.

• They move to the side closest to the balloon.

Why can't a charged balloon pick up a whole piece of paper?

• The electric force is too small to overcome gravity.

• The paper is not polarized.

• The paper is too heavy.

• The balloon loses its charge.

How does polarization differ in conductors compared to insulators?

• Conductors have a larger polarization effect.

• Insulators have a larger polarization effect.

• Insulators allow free movement of electrons.

• Conductors have a smaller polarization effect.
