Question 1 Report

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?

864 NC-1

150 NC-1

144 NC-1

18 NC-1

Answer Details

E = $\frac{F}{q}$ and Q1 = 50μF, E1 = 360μF, E2 = ?, Q2 = 120μF
Using E = $\frac{F}{q}$ .
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 $^{- 1}$
