Two charges +q and-q are kept apart, Then at any point on the right bisector of line joining the two charges

A

The electric field strength is zero

B

The electric potential is zero

C

Both electric potential and electric field strength are zero

D

Both electric potential and electric field strength are non-zero

Text Solution

Verified by Experts

The correct Answer is:
(a)
Electric potential at any point is ,
` V_(P) = V_(1) + V_(2) = 1/4 pi epsilon_(0) q/r + 1/4 pi epsilon_(0) -q/r = 0`
