When ultraviolet light is incident on a photocell, its stopping potential is `V_(0)` and the maximum kinetic energy of the photoelectrons is `K_(max)`. When X-rays are incident on the same cell, then:

Options

A. `V_0 and K_(max)` both increase.
B. `V_0 and K_(max)` both decrease.
C. `V_0` increases but `K_(max)` remains the same.
D. `K_(max) ` increases by `V_0` remains the same.

Answer

A
