Answer: 6.25 × 10^18
Explanation:
The body with 1 C charge has n1 = 6.25 × 10^ 18 electrons.
when the body is neutral, i.e, Q = 0 .
we know Q = n2e,
n2= Q/e
n2 = 0/e
n2 = 0.
which means the no. of electrons present in the body is equal to the no. of protons.
We can calculate the no. of extra electrons by n2 - n1 = 6.025 × 10^18.
