Question

An accelerated electron has energy of $9.6x{10}^{-18}J$. Express the energy in electron volts (eV)

Answer 1

Given:

Energy of electron= $9.6x{10}^{-18}J$

To express the energy in electron volts :

Formula used: $1eV=1.6\times {10}^{-19}J$

$1J=\frac{1}{1.6\times {10}^{-19}}eV$

$9.6\times {10}^{-18}J=\frac{9.6\times {10}^{-18}}{1.6\times {10}^{-19}}eV$

$=60eV$

Answer:

Hence, $9.6x{10}^{-18}J$ $=60eV$
