Question

if a body loses 10⁹ electrons per second calculate the time when it will lose 1 couloumb of charge​

Answer 1

Answer:

In one second 109 electrons move out of the body.

the charge given out in one second is 1.6×10-19×109C=1.6×10-10C. The time required to accumulate a charge of 1 C can then be estimated to be 1C÷(1.6×10-10C/s)=6.25×109s=6.25×109÷(365×24×3600) years = 198 years

Answer 2

In one second 109 electrons move out of the body. Therefore the charge given out in one second is 1.6×10-19×109C=1.6×10-10C. The time required to accumulate a charge of 1 C can then be estimated to be 1C÷(1.6×10-10C/s)=6.25×109s=6.25×109÷(365×24×3600) years = 198 years.
