Question

1. How many electrons have to be removed from a metallic
piece so that it can acquire a charge of luc.
2​

Answer 1

Explanation:

6.25×1018 electrons

Using  Q=ne

where Q = charge

n = number of electrons

e = charge on one electron

So, n=eQ=1.6×10−191C

=0.625×1019

=6.25×1018 electrons.
