Question

When 10¹⁹ electrons are removed from a neutral metal plate through some process, the electric charge on it is ______

Options

• -1.6 C

• +1.6 C

• 10⁺¹⁹ C

• 10^-19 C

Answer 1

When 10¹⁹ electrons are removed from a neutral metal plate through some process, the electric charge on it is +1.6 C.

Explanation:

By using Q = ne

Q = `10^19 xx 1.6 xx 10^-19`

Q = +1.6 C
