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

1 keV

D

920 keV

Text Solution

Verified by Experts

The correct Answer is:
C
The charge on a proton is equal to e, the electronic charge . The potential differnece is V=1 kV. Hence the kinetic energy of the proton is E=1 keV.
