Assertion (A): An electron and a proton ...

Assertion (A): An electron and a proton moving with same velocity enters a magnetic field. The force experienced by the proton is more than the force experienced by the electron.
Reason (R): The mass of proton is more than the mass of the electron.

A

Both A and R are true and R is the correct explanation of A

B

Both A and R are true but R is NOT the correct explanation of A

C

A is true but R is false

D

A is false and R is true

Text Solution

Verified by Experts

The correct Answer is:
D
`vecF = q (vecupsilon xx vecB)`
So, the force is mass independent. So, the assertion is false.
Proton is obviously heavier than electron. So, reason is true. But reason does not explain the assertion.
