How much work does an electric field do in moving a proton from a point with a potential of +125V to a point where it is -55V? Express your answer in both joules and electron-volts.

Proton moving from a point with Potentialdifference + 125 V to - 55 V

            Potential difference ?V = 125 V + 55 V
                                                  = 180 V

      Work done is q ?V

                                   W = 1.6 *10^-19 C * 180 V
                                           = 288 *10^-19 J

                                        W = 288 *10^-19 J / 1.6 *10^-19 C
                                                = 180 e V

A proton is released from rest inside a region of constant, uniform electric field ?1 pointing due north. 34.8 s after it is released, the electric field instantaneously changes to a constant, uniform electric field ?2 pointing due south. 8.49 s after the field changes, the proton has returned to its starting point. What is the ratio of the magnitude of ?2 to the magnitude of ?1? You may neglect the effects of gravity on the proton.
