Assertion : A beam of protons is moving ...

Assertion : A beam of protons is moving towards east in vertically upward magnetic field. Then, this beam will deflect towards south.
Reason : A constant magnetic force will act on the proton beam.

A

If both Assertion and Reason are true and the Reason is correct explanation of the Assertion.

B

If both Assertion and Reason are true but Reason is not the correct explanation of Assertion

C

If Assertion is true, but the Reason is false.

D

If Assertion is false but the Reason is true.

Text Solution

Verified by Experts

The correct Answer is:
C
By changing the directioin of velocity direction of magnetic fore will change. So it is not a constant force.
