Question

if 10^7 electrons are removed from a body then what is the amount of charge acquired by the body

Answer 1

10^7 electrons are removed from the body.

It means , that the body will get positive charge of equal magnitude of charge on 10^7 electrons.

1 electron has charge of -1.6×10^-19 C

So 10^7 electrons will have charge of magnitude 1.6×10^-19 ×10^7C

=1.6×10^-12 c

so body will get +1.6×10^-12 C of charge
