E D Problem 1: A uniform electric field is directed from left to right as shown in the figure below: AC B •Which point, A, B, or C, is at a higher potential? hich point is at the lowest potential? Which point is at the lowest potential? •Draw in the equipotential surfaces at points A, B, and C. •A proton is placed at point A and released. Which way does it move? •How much work is done by the field if the proton moves from point A to B? Write an xpression for this expression for this. •How is the change in the proton’s EPE related to your answer in part e? Is it positive or negative? •The proton now moves from point A to point D, which sits directly above A. How much ork did the electric field do on the proton? work did the electric field do on the proton? •An electron is placed at point C and released. Which way does it move? •What can you say about the electron’s EPE and KE at point B compared to point C?
