Photon of 5.5 eV energy falls on the surface of the metal emitting photoelectrons of maximum kinetic energy 4.0 eV. The stopping voltage required for these electrons are

A

5.5 V

B

1.5V

C

9.5V

D

4.0V

Text Solution

Verified by Experts

The correct Answer is:
D
As `K_(max)=4.0eV` hence stopping potential `V_(0)=(K_(max))/(e)=4.0V`
