In the region shown in the image, there is a uniform electric field of magnitude 39.3 N/C which points in the positive x -direction. Points 2, 3, and 4 are all 0.497 m away from point 1, and the angle p = 31.1. -02 Calculate the following potential differences V, - V,, where i and j indicate the numbered points. V2 - VI = -19.53 V V3 - V1 = 0 V 13.48 VA - VI =
