Choose the correct statement(s)

A. In photo electric effect, the minimum negative potential to the plate A for which photocurrent is zero is called saturation potential.
B. Maximum kinetic energy of photoelectrons is directly proportional to intensity of incident radiation.
C. $K_{max} = eV_o$
D. Photocurrent becomes zero at stopping potential.
E. For different intensities of light, stopping potential is different.

Choose the correct answer from the options given below:

C & D only

The correct answer is Option (1) → C & D only

(C) The stopping potential $(V_o)$ is related to maximum K.E. by,

$K_{max}=eV_o$

(D) At the stopping potential, the emitted photoelectrons are unable to reach the Anode due to negative potential, and the photocurrent becomes zero.
