If 10^9 electrons move out of body every second then what is time taken to charge the body of 1 column?

As charge on one electron is 1.6*10^-19 . So per sec charge out from body is 1.6*10^-10. so for 1 coulomb charge time is given by (1.6*10^-10)t = 1. So t = 6.25*10^9 sec.Hope it clears. If still u have doubts then please clarify. If u like answer then please approve the answer.
