Vedclass · Answer

(C) The charge on the body is given by $q = -3.2 \mu C = -3.2 	imes 10^{-6} \ C$.According to the quantization of charge,$q = ne$,where $n$ is the number of electrons and $e$ is the elementary charge $(e = -1.6 	imes 10^{-19} \ C)$.Therefore,the number of excess electrons is given by $n = \frac{q}{e}$.$n = \frac{-3.2 	imes 10^{-6} \ C}{-1.6 	imes 10^{-19} \ C}$.$n = 2 	imes 10^{13}$.

$A$ body has a charge of $-3.2 \mu C$. The number of excess electrons will be
