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

A

`1840 keV`

B

`1//1840 keV`

C

`1keV`

D

`920 keV`

Text Solution

Verified by Experts

The correct Answer is:
C
The enegry acquired by anu charged particle (irrespective of its mass) is always equal to the product of charge and potential difference. Since the charge on a proton is equal to that of an electron,
`KE = (e) (1kV) = 1keV`
