The electric field in a particular region of space is found to be uniform, with a magnitude of 400 N/C and parallel to the +y direction. (a) What is the change in electric potential energy of a charge if it is moved from (x, y) = (20 cm, 45 cm) to (5 cm, 30 cm)? (b) What is the change in electric potential energy if the charge is moved the same distance along the x axis?
