A proton is about `1840` times heavier than an electron. When it is accelerated by a potential difference of `1 kV`. Its kinetic energy will be

A

`1840 keV`

B

`1 keV`

C

`1//1840 keV`

D

`920 keV`

Text Solution

Verified by Experts

The correct Answer is:
B
When potential difference is `V` ,energy is given by
`E = qV = eV` `(because q_(p) = q_(e ) = e)`
The above equation shows that kinetic energy is independent of mass of charged particle.
Hence , kinetic energy is `1 keV`.
