Assertion : The stopping potential depends on the frequency of incident light.
Reason : The stopping potential is related to maximum kinetic energy by `eV_(0)=K_(max)`.

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
(a) : The stopping potential is related to the maximum kinetic energy of electrons emitted as `eV_(0)=(1)/(2)mv_(max)^(2)=K_(max)`
Now, `K_(max)=hv-phi_(0)`. Therefore, stopping potential `V_(0)` depends on the frequency of incident light.
