Look up the definition of the unit of energy called an "electron volt."

Joules

I think the anser has to be with the units Jouls and using the formula w=v*Q

???

I understand the concept of the electron volt.. but why is the answer 1.5 Mev.

The energy acquired by an electron when accelerated through a potential difference of 1 volt is 1 electron volt. The energy acquired by an electron when accelerated through a potential difference of 1.5 MV is 1.5 MeV.

Re: Thank you, Warren.

Does the answer make complete sense? I want to make sure you understand how what I just said comes directly from the definition of the eV.
