Question

The absolute charge of an electron is

• A. $-1.6\times {10}^{-19}\mathrm{C}$
• B. $+1.6\times {10}^{-19}\mathrm{C}$
• C. $1.6\times {10}^{-19}\mathrm{C}$
• D. $16\times {10}^{-19}\mathrm{C}$

Answer 1

The correct option is A

$-1.6\times {10}^{-19}\mathrm{C}$

Explanation for correct option

(A) Electron is sub-atomic particle of atom having negative charge and present outside the nucleus. The absolute charge of an electron is $-1.6\times {10}^{-19}\mathrm{C}$.

Thus, the absolute charge of an electron is $-1.6\times {10}^{-19}\mathrm{C}$.

Therefore, option (A) is correct option.
