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 (A) and (R) are correct and (R) is the correct explanation of(A).

B

If both (A) and (R) are correçt, but (R) is not the correct explanation of (A).

C

If (A) is correct, but (R) is incorrect.

D

If both (A) and (R) are incorrect.

Text Solution

Verified by Experts

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