Why does a charged glass rod attract a piece of paper ?

Text Solution

Verified by Experts

Paper is a dielectric. When a positively charged glass rod is brought near it, atoms of paper get polarised , with center of negative charge of atoms coming closer to glass rod. Therefore, force fo attraction `(F_(a))` between glass rod and piece of paper becomes greater than the force of repulsion `(F_(r))` between the glass rod and the piece of paper towards the glass rod.
