Net charge on object having 9 x 1013 protons and 6 x 1013 electrons is

1.	Net charge on object having 9 x 1013 protons and 6 x 1013 electrons is (A) – 4.8 uc(B) 4.8 MC(C) 4.8 C(D) 3 x 1.6 x 10-19 C
Answer» CHARGE on 1 proton =1.610^-19charge on 910^13= 1.610^-19 910^13 = 14.4 10^-6SimilarlyCharge on 1 ELECTRON = -1.610^-19charge on 610^13= - 1.610^-19 610^13= -9.610^-6Net charge= Charge of electron + Charge of proton = -9.610^-6 + 14.410^-6 = 4.8 columb Correct option is C
