A comb rubbed with dry hair, can attract small pieces of paper because......

A

comb is a conductor.

B

paper is a conductor.

C

atoms of paper get polarised by charged comb.

D

comb attains the property of magnetism.

Text Solution

Verified by Experts

The correct Answer is:
C
When we pass comb through dry hair, it gets electrified. Now when this comb is brought nearer to small pieces of paper, its atoms get polarised where charge gets induced on the pieces of paper with polarity opposite to that of comb. Hence, small pieces of paper get attracted towards the comb.
