Question

An object has a total charge of 3.2 x 10^2 C how many electrons are present in the object

Answer 1

Hey Mate
your answer is here

given that
total charge = 3.2×10^2c

so,

no. of electrons = 3.2×10^2/1.6×10^-19 = 2×10^21

Answer 2

since the end of the object Falls between the 10 - and 11 - and give marks we are so of the first how many electric needed for a total charge of
