Point charges +4q, -q are kept on the x-...

Point charges `+4q, -q` are kept on the `x`-axis at points `x=0,x=a` and `X=2a` respectively, then

A

Only `q` is in stable equilibrium

B

None of the charges are in equilibrium

C

All the charges are in unstable equilibrium

D

All the charges are in stable equilibrium

Text Solution

Verified by Experts

The correct Answer is:
C
Force on each charge is zero. But if any of the charge is displaced, the net force starts acting on all of them.
