PhysicsEasysingle choice

Light of wavelength $400 nm$ is incident continuously on a Caesium ball (work function $1.9 eV$ ). The maximum potential to which the ball will be charged is

Options:

Answer:

Solution:

$e V_{s} = \frac{12400}{4000} eV - 1.9 eV = 3.1 - 1.9 eV$

$e V_{s} = 1.2 eV$

$V_{s} = 1.2 V$
