A charge 50 µc has electric field strength of 360 NC-1 at a certain point. The electric field strength due to another charge 120 µc kept at the same distance apart and in the same medium is?

Answer Details

E = $\frac{\text{F}}{\text{q}}$ and Q1 = 50μF, E1 = 360μF, E2 = ?, Q2 = 120μF
Using E = $\frac{\text{F}}{\text{q}}$.
So we have F = Q $\times$ E
F = 50 $\times$ 10${}^{-6}$ $\times$ 360 = 0.018N
When E2 = F/q
$\frac{0.018}{120\times {10}^{-6}}$ = 150NC${}^{-1}$
