Question 93

Two plastic rods, R R\,R and SSS, are oppositely charged. Rod R R\,R is positively charged and hangs freely.

The negatively charged rod S S\,S is brought near end A A\,A of rod RRR, and then near end B B\,B of rod RRR.

What happens to the rods in each position?

A

near end AAA: they attract; near end BBB: they attract

B

near end AAA: they attract; near end BBB: they repel

C

near end AAA: they repel; near end BBB: they attract

D

near end AAA: they repel; near end BBB: they repel
