Q. If $10^{10}$ electrons are acquired by a body every second, the time required for the body to get a total charge of 1 C will be
A) Two hours
B) Two days
C) Two years
D) 20 years
Explanation
(d) $\frac{q}{t} = 10^{10} \times 1.6 \times 10^{- 19}$ and $q = 1C$
So, $\frac{1}{t} = 1.6 \times 10^{- 9}$
$t = \frac{10^{10}}{16}sec \Rightarrow t =$ 20 years
