Question

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

Answer 1

Answer: (B)

At equitorial point
$E_e=\frac{1}{4\pi {\epsilon }_0}\frac{p}{r^3}$
(directed from $+q$ to $-q$ ) and $V_e=0$
