Question

Two-point charges reacted with each other to produce 4.32 x 10⁻⁴ J. the magnitude of q is 30 nC with a distance from the point charge of 19 cm. Find the magnitude of the point charge

Answer 1

Answer

The another charge is given by

$Q=\frac{4.32*10^{-4}*0.19}{9*10^9*30*10^{-9}}\\=3.04nC$
