Question

Two charge of magnitude +q and -3qare placed 100 cm apart. The distance from +qbetween the charge where the electrostatic potential is zero is :

Options

A.25 cm
B.50 cm
C.75 cm
D.80 cm

Solution

         
Suppose x is the required distance from q, then
= 0
After solving for x, we get x = m
