Question

A negatively charged plastic comb is brought close to, but does not touch, a small piece of paper. If the comb and the paper are attracted to each other, the charge
on the paper

Answer 1

The charge on the paper is likely positive. When a negatively charged object is brought close to a neutral object, it can induce a separation of charges in the neutral object. This means that the negatively charged object repels electrons in the neutral object, leaving a net positive charge on the side of the object facing the negative charge. Therefore, the paper would acquire a positive charge and be attracted to the negatively charged comb.
