Question : 121 of 160

Marks: +1, -0

Which of the following equations does represent the velocity (v) of the ejected electrons when a metal is made to strike with light of frequency υ and threshold frequency of the metal is υ0 ?
(me = mass of electron and h is Planck’s constant)

v = √
h(υ−υ0)
me
v = √
2h(υ−υ0)
me
v = √
h(υ−υ0)
2me
v = √h(υ−υ0)me
