(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

I'm not even sure the problem is about matterwave:

A particle of mass m and charge e is accelerated by a potential difference V. Find the wavelength of the particle. Show that this result agrees with the classical one when the non relativistic limit is taken.

2. Relevant equations

Not sure, but I think that [tex]\lambda _B=\frac{h}{mv}[/tex] where m is the relativistic mass, i.e. [tex]m=\gamma m_0[/tex].

Maybe [tex]F=qE[/tex]?

3. The attempt at a solution

I'm not really sure how to find the motion equation of the particle and I need its velocity in order to calculate its de Broglie's wavelength. F=qE.

[tex]\Delta V =\int _A^b \vec E d \vec l[/tex]... I don't go anywhere that way.

I've no idea what I'm missing.
