Question

Calculate the stopping potential if the maximum kinetic energy of photoelectrons emitted by a photocell is 4eV.

Answer 1

Answer:

Explanation:

We know that

Kinetic energy max = e charge × stopping Potential

4ev /1.6 ×10^-19 = stopping Potential

Answer 2

The stopping potential of the photo electron is 4 volts.

Explanation:

The maximum kinetic energy of photo electrons emitted by a photocell is 4 eV.

To find,

The stopping potential.

Solution,

The kinetic energy of the photo electron is given by :

$K=eV_o$

$V_o$ is stopping potential

$4e=eV_o$

$V_o=4\ volts$

So, the stopping potential of the photo electron is 4 volts.
