The figure below shows two points in an E-field: Point 1 is at (x1, y1) = (5,4) in m, and Point 2 is at (x2,y2) =(12,12) in m. The Electric Field is constant, with a magnitude of 56 V/m, and is directed parallel to the +x-axis. The potential at point 1 is 1100 V. Compute the potential at point 2.
Compute the work required to move a negative charge of Q = -562 μC from point 1 to point 2.
