Question

Why is a neutral paper piece attracted to a charged comb?

Options

• Its surface becomes slightly conducting and shields the comb.

• Friction transfers electrons from the paper to the ground.

• Its positive and negative charges rearrange slightly by polarisation, leading to net attraction.

• Its charges remain fixed in their original arrangement and create a spark discharge.

Answer 1

The charged comb causes the paper's bound positive and negative charges to rearrange slightly. The nearer side is oppositely influenced, producing a net attraction.
