In 1 gm of a solid, there are atoms. If one electron is removed from everyone of 0.01% atoms of the solid, the charge gained by the solid is (given that electronic charge is )????
Number of electrons removed in total = (0.01/100)×5×10^21 = 5×10^17
Charge on each electron = -1.6×10^-19 C
Total charge removed = (5×10^17) × (1.6×10^-19)C = -0.08 C
Thus charge acquired = +0.08 C
