Question

if an electron having kE 2 ev is accelerated through the potential difference of 2 volt calculate wavelength with an electron

Answer 1

Hey friend...

I will tell you the process of doing this. Firstly you try and if you will not get then you can ask to me.

So firstly change the kinetic energy for eV to Joules and then apply the formula

$\sqrt{h \div 2evm}$

Here h is plank's constant , e is charge , v is potential difference and m is mass

You will get the answer

One more thing to say... It is not a physics question, it's of chemistry
