1. The problem statement, all variables and given/known data How much work does the electric field do in moving a proton from a point with a potential of +155V to a point where it is -75V. Express your answer in both joules and electron volts. 2. Relevant equations W = -qV 3. The attempt at a solution I know that q=(1.6E-19) but I am not for sure how to go about incorporating my two potentials. Can someone give me some help? I thank you in advance!
