(4%) Problem 1: Two points, point 1 and point 2, are located inside a region with an electric field pointing to the left, as shown in the figure. 1 50% Part (a) If a proton is moved from point 1 to point 2, how will the potential energy of the charge-field system change? How will the potential change? Increases / Increases Correct! 50% Part (b) If, instead, an electron is moved from point 1 to point 2, how will the potential energy of the charge-field system change? How will the potential change? O Decreases / Decreases O Increases / Increases O Decreases / Increases O Increases / Decreases
