An object has a charge of 1 C and gains 5-0 x 10¹⁸ electrons. The net charge on the object becomes

The charge of one electron is − 1.6 × 10−¹⁹ C. The object gains
5.0 × 10¹⁸ electrons, resulting in a charge change of:
q = (5.0 × 10¹⁸) × (−1.6×10⁻¹⁹) = −0.80C
Net charge = 1C−0.80C= +0.20C.
Correct answer: (d) +0.20 C.
