two identical rings of radius `R` have uniformly distributed charge `Q(Qgt0)` each. Both the rings are fixed and are placed coaxially separated by a distance of R. if a small positive point charge is placed at the mid point and is displaced slightly along the axis then,

A

it will not perform oscillation

B

it will perform oscillation but no SHM

C

it will perform SHM

D

answer will depend on the magnitude of the charge.

Text Solution

Verified by Experts

The correct Answer is:
A

Ring 1 will apply more repulsive force
so, charge will keep moving in same direction.
