Question

Calculate the kinetic energy in electron volt of a charge of 8 x10 $^{- 19}$ C when it is accelerated through a potential difference of 200 V:

Open in App

Solution

Given,

Charge of the electron = $8 \times 10^{- 19}$

$p D = 200 V$

So, the $K E = e V$

Where e is the charge and v is the PD

Thus,

$K E = 8 \times 10^{- 19} \times 200$

$K E = 16 \times 10^{- 17} J$
