Assertion: If frequency of incident light is doubled, the stopping potential will also become two times
Reason: Stopping potential is given by ` V_0 = (h)/(e ) (v-v_0)`

A

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

B

If both Assertion and Reason or 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:
D
`eV_0 = hv - hv_0`
or `V_0 =(h)/(e ) (V -v_0)`
`V_0 = (h)/(e ) (2V -v_0)+ (hv_0)/(e )`
`= 2V_0 = (hv_0)/(e ) gt 2V_0`
