The speed of a proton moving in a electric field changes from vi to vf over a certain time interval. Let the mass and the charge of the proton be denoted as mp and e. Through what potential difference did the proton move during the interval?
- mp2(v2f-v2i)
- mp2e(v2f-v2i)
- mp2(vf-vi)
- mp2e(vf-vi)
