A cube of side 'a' has a charge Q at each of its vertices, what is the potential due to this charge array at the centre of the cube? |
$\frac{2Q}{\sqrt{3}πε_0a}$ $\frac{4Q}{\sqrt{3}πε_0a}$ $\frac{Q}{2\sqrt{3}πε_0a}$ $\frac{8Q}{\sqrt{3}πε_0a^2}$ |
$\frac{4Q}{\sqrt{3}πε_0a}$ |
The correct answer is Option (2) → $\frac{4Q}{\sqrt{3}πε_0a}$ |
