When monochromatic radiation of intensity I falls on a metal surface, the number of photoelectrons and their maximum kinetic are N and T respectively. If the intensity of radiation is 2 I, the number of emitted electrons and their maximum kinetic energy are respectively.

A

N and 27

B

2N and T

C

2N and 27

D

N and T

Text Solution

Verified by Experts

The correct Answer is:
B
The number of photoelectrons ejected is directly proportional to the intensity of incident  light. Maximum kinetic energy is independent of intensity of incident light but depends upon the frequency of light. Hence, option (b) is correct.
