Question

An electron is accelerated through a potential difference of 300V.What is its energy in election volt?

Answer 1

hey mate!

kinetic energy of electron = qv

k.E = 1.6 X 10^-19 X 300

= 48 X 10^-18 eV

Answer 2

The energy of the electron is $300\ eV$.

Explanation:

Given that,

An electron is accelerated through a potential difference of 300 V, V = 300 V

We need to find the energy in electron volt. We know that the energy in terms of potential difference is given by :

$E=qV$

Here, q = e

$E=eV$

$E=1.6\times 10^{-19}\times 300$

$E=4.8\times 10^{-17}\ J$

or

$1\ eV=1.6\times 10^{-19}\ J$

$E=300\ eV$

So, the energy of the electron is $300\ eV$. Hence, this is the required solution.
