Q. Ten electrons are equally spaced and fixed around a circle of radius $R.$ Relative to $V = 0$ at infinity, the electrostatic potential $V$ and the electric field $E$ at the centre $C$ are
A) $V \neq 0\ and\ \overrightarrow{E} \neq 0$
B) $V \neq 0\ and\ \overrightarrow{E} = 0$
C) $V = 0\ and\ \overrightarrow{E} = 0$
D) $V = 0\ and\ \overrightarrow{E} \neq 0$
Explanation
(b) At centre $E = 0,\ V \neq 0$
