A gold coin has a charge of $+10^{-4} C$. The number of electrons removed from it is:

AnswerClick to flip back

$625 \times 10^{12}$

💡 Explanation:

The total charge of electrons removed from the coin would be equal to the positive charge acquired by the coin.

Thus, $10^{-4}C=n\times 1.6\times 10^{-19}C$

$\implies n=625\times 10^{12}$
