3. How much work does the electric field do in moving a proton from a point with a potential of Vo = + 145 V to a point where it is Vy = - 45 V? (3 pts)

When moving a distance d in a uniform electric field, a proton acquires 5.0 V of electric potential. If three protons are moving the same distance in the same uniform electric field, the electric potential each of them acquires is O 3.0 V. 5/3 V. OV. O 5.0 V. O 15 V.
