Explanation:
It is given that,
Charge,![Q_1=5.7\ nC=5.7\times 10^{-9}\ C](/tpl/images/0054/8037/06944.png)
Charge,![Q_2=-2.3\ nC=-2.3\times 10^{-9}\ C](/tpl/images/0054/8037/e3e31.png)
Distance between charges, d = 45 cm = 0.45 m
We need to find the electric potential at a point midway between the charges. It is given by :
Midway between the charges means, r = 22.5 cm = 0.225 m
So, the electric potential at a point midway between the charges is 136 volts. Hence, this is the required solution.
