31. A proton is placed in an electric field between two parallel plates. If the plates are 6.0 cm apart and have a potential difference between them of 7.5 x 101 v, how much work is done against the electric field when the proton is moved 3.0 cm parallel to the plates? [0] 32. In the previous question, how much work would be done against the electric field if the proton was moved 3.0 cm perpendicular to the plates? [6.0 x 10-18 J]
