Question

Determine the electric potential at a point P which is 2.00 m from a point charge of -5.00µC.

Answer 1

Given data

Charge is $q=-5.00*10^{-6} C$

The electric potential at a point P which is 2.00 m from a point charge of -5.00µC is

$V=\frac{kq}{r}=\frac{(9*10^9)(-5.00*10^{-6})}{2.00 }$

$=-2.25*10^4 V$
