Question

How many electrons will have a charge of 100 coulomb?

Answer 1

one coulomb of charge has the equivalent charge of 6.25×10^18 electrons.this is determined from the value of charge on one electron and the value of charge for one coulomb. I think now you are able to do it by yourself.

Answer 2

e=-1.6×10⁻₁₉

charge on the object= Ne

N=charge on the object divided by electron=1 divided by 1.6×10⁻₁₉

=6.25×10 too the power of 18
