Assertion: An electron and proton enters a magnetic field with equal velocities, then, the force experienced by the proton will be more than electron.
The mass of proton is `1837` times more than electron.

Options

A. If both assertion and reason are true and the reason is the correct explanation of the assertion.
B. If both assertion and reason are true but reason is not the correct explanation of the assertion
C. If assertion is true but reason is false.
D. If assertion is false but reason is true.

Answer

D

Explanation

The force experienced by a charge particle in a magnetic field is given by , `vecF = q (vecv xx vecB)` which is independent of mass. As q, v and B are same for both the electron and proton, both will experience same force.
