Question

Two charges q and q are kept apart. Then at any point on the perpendicular bisector of line joining the two charges:
  1. the electric field strength is zero
  2. the electric potential is zero
  3. both electric potential and electric field strength are zero
  4. both electric potential and electric field strength are non-zero

A
both electric potential and electric field strength are non-zero
B
the electric field strength is zero
C
the electric potential is zero
D
both electric potential and electric field strength are zero
Solution
Verified by Toppr

We know voltage is given by Kqr
All the points on perpendicular bisectore are at equidistant from the two points A and B.
Potential=Kqr+K(q)r
=0
