Assertion : The specific charge of positive rays is not constant.
Reason : The mass of ions varies with speed.

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 the assertion and reason both are false.

Text Solution

Verified by Experts

The correct Answer is:
B
The specific charge (e /m) of the positive rays is not universal constant because these rays may consist of ions of different elements
