Calculating Electron Energy from Potential Difference

[soso]

Currents-- Please Help

An electron is accelerated from rest through a potential difference of 1.5Mv. what is the final energy of the electron.

 

[chroot]

1.5 MeV.

Confused

Sorry.. i do not understand the answer... can u please provide more detail.. sorry for the inconvenience... thank you.

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

 

[chroot]

Do what I ask -- I'm not misleading you. Look up the unit called the "electron volt."

In fact, here's a definition:

?

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

 

[chroot]

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.

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.
