Vedclass · Answer

(C) The charge $q$ is given by $q = ne$,where $n$ is the number of electrons and $e$ is the elementary charge $(1.6 	imes 10^{-19} \, C)$.Since the body is given a positive charge of $+2 \, C$,it means electrons are removed from the body.The number of electrons removed is $n = \frac{q}{e} = \frac{2}{1.6 	imes 10^{-19}} = 1.25 	imes 10^{19}$.The change in mass $\Delta m$ is equal to the mass of the removed electrons: $\Delta m = n 	imes m_e$,where $m_e = 9.1 	imes 10^{-31} \, kg$.$\Delta m = (1.25 	imes 10^{19}) 	imes (9.1 	imes 10^{-31} \, kg) = 11.375 	imes 10^{-12} \, kg$.Therefore,the change in mass is approximately $11.37 	imes 10^{-12} \, kg$.

Find the change in mass of a body if it is given a $+2 \, C$ charge.
