Point charges 
and 
are kept on the 
‐axis at point 
and 
respectively. Then
A
only 
is in stable equilibrium
is in stable equilibrium
B
all the charges are in stable equilibrium
C
all of the charges are in unstable equilibrium
D
none of the charges is in equilibrium
Text Solution
Verified by ExpertsThe correct answer is:
C
Net force on each of the charge due to the other charges is zero. However, disturbance in any direction other than along the line on which the charges lie, will not make the charges return.
