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

A

1840 keV

B

1/1840 keV

C

1keV

D

920 keV

Text Solution

Verified by Experts

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