How many electrons would have to be removed from a coin to leave it with a charge of +1.5 × 10^-5 c?

leave out with a charge of

Explanation:

We have given total charge

We know that charge on one electron =

We have to find the total number of electron in total charge

So , here q is total charge, n is number of electron and e is charge on one electron

So

So leave out with a charge of
