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

1/1840 ke V

C

1 keV

D

920 keV

Text Solution

Verified by Experts

The correct Answer is:
C
Energy acquired by electron (as K.E.) on being accelerated by a potential difference of 1kV = 1keV. As proton has the same charge and as energy = potential difference `xx` charge, hence proton will have the same kinetic energy
