Question

Six point charges are placed at the vertices of a regular hexagon of side $a$ as shown. If $E$ represents electric field and $V$ represents electric potential at $O$, then

• A. $E=0$ but $V \neq 0$
• B. $E \neq 0$ but $V=0$
• C. $E=0$ and $V=0$
• D. $E \neq 0$ and $V \neq 0$

Answer 1

Answer: (C)

$V=\frac{3 k q}{r}-\frac{3 k q}{r}=0$
