? 2 3 4 5 A uniform electric field E = 410 N/C (created by charges not shown in the picture) points in the +x-direction. A positive charge Q = +0.53 C is moved around isosceles right triangles (through various paths as shown) with sides ab = db = cb = 6.7 cm. a 1) When the charge is moved from point a to point c along a straight path (through point b), what happens to the electrical potential energy of the charge Q? The potential energy increases. The potential energy decreases. The potential energy remains the same.
