Relation between the stopping potential

{V_0}

of a metal and the maximum velocity v of the photoelectron is

View answer and explanation

Correct option: A

{V_0} \propto {V^2}

Option A (

{V_0} \propto {V^2}

) is correct because the stopping potential is related to the maximum kinetic energy of the photoelectrons, which is proportional to the square of their velocity.
