Assertion : The characteristics of catho...

Assertion : The characteristics of cathode rays do not depend upon the material of electrodes and the nature of the gas present in the cathode ray tube.
Reason : Cathode rays consist of negatively charged particles, called electrons.

A

If both assertion and reason are true and reason is the correct explanation of assertion.

B

If both assertion and reason are true but reason is not the correct explanation of assertion.

C

If assertion is true but reason is false.

D

If both assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
A
Cathode rays consist of electrons which are the basic constituent of all the atom and hence their characteristics do not depend upon the material of electrodes and nature of the gas present in the cathode ray tube.
