Q. 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.
Explanation
(b) At equitorial point
$E_{e} = \frac{1}{4\pi\varepsilon_{0}}\frac{p}{r^{3}}$
(directed from +q to –q) and $V_{e} = 0$.
