Question

Question : What is the Electric potential energy in electron volts of an electron which is present in an electric potential V = 6.78 Volts?​

Answer 1

Given:

An electron which is present in an electric potential V = 6.78 Volts.

To find:

Electric Potential Energy in eV ?

Calculation:

The potential energy refers to the energy present in a charge kept in a field with a certain electric potential.

So, this value can be calculated by multiplying the charge value with the electrostatic potential value.

$\sf \therefore \: E = e \times V$

$\sf \implies\: E = (1.6 \times {10}^{ - 19} \times 6.78) \: joule$

$\sf \implies\: E = \dfrac{(1.6 \times {10}^{ - 19} \times 6.78)}{1.6 \times {10}^{ - 19} } \: eV$

$\sf \implies\: E = 6.78 \: eV$

So, electrostatic potential energy of the electron is 6.78 eV.
