Three isolated equal charges are placed at the three comers of an equilateral triangle as shown in figure. The statement which is true for net electric potential $V$ and net electric field intensity $E$ at the centre of the triangle is

A

$E=0, V=0$

B

$V=0, E \neq 0$

C

$V \neq 0, E=0$

D

$V \neq 0, E \neq 0$

Solution

(c)

$E_{\text {net }}=0$

$V_{\text {net }}=3\left(\frac{k q \sqrt{3}}{l}\right)=3 \sqrt{3} \frac{k q}{l}$
