easy

An electron (charge = $1.6 \times {10^{ - 19}}$ $coulomb$) is accelerated through a potential of $1,00,000$ $volts$. The energy required by the electron is

A

$1.6 \times {10^{ - 24}}\, joule$

B

$1.6 \times {10^{ - 14}}\,\,erg$

C

$0.53 \times {10^{ - 14}}\,joule$

D

$1.6 \times {10^{ - 14}}\,joule$

Solution

(d) Energy $ = 1.6 \times {10^{ – 19}} \times 100000 = 1.6 \times {10^{ – 14}}J$
