Q. Two equal and opposite point charges each of one coulomb are placed at a distance of one metre from each other. The potential at a point midway between the two point charges will be

zero volt

2 volt

1 volt

$2$ volt

Potential is a scalar quantity.
Potential at point $O$ due to the given charge distribution is
$V = \frac{1}{4 π ε _{0}} [\frac{1}{0.5} + \frac{( - 1 )}{0.5}] =$ zero volt
