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
$E_{e}=\frac{1}{4 \pi \varepsilon_{0}} \frac{p}{r^{3}}$
(directed from $+q$ to $-q$ ) and $V_{e}=0$
