Question

A proton has a mass of $1.67\times {10}^{-27}kg$ and charge $1.6\times {10}^{-19}$ coulomb. If the proton is to be acceleration through a potential difference of one million volt, them the $KE$ is:

• A. $1.6\times {10}^{-14}J$
• B. $1.6\times {10}^{-13}J$
• C. $1.6\times {10}^{-25}J$
• D. $3.2\times {10}^{-13}J$

Answer 1

The correct option is A $1.6\times {10}^{-14}J$

Hence, option $\left(A\right)$ is correct answer.
