Question

Proton has a charge of $\times$ ${10}^{-19}$ C

• A. 1.6022
• B. -1.6022
• C. -9.1094

Answer 1

The correct option is A 1.6022

Goldstein discovered the positively charged particles called protons. According to his canal rays experiment, the charge on the proton has the same magnitude as that of an electron but of opposite sign.

We know,
Charge on an electron = - 1.6022 $\times$ ${10}^{-19}$ C
Therefore,
Charge on proton = +1.6022 $\times$ ${10}^{-19}$ C
