The figure below shows two points in an E-field: Point1 is at (x1,y1) = (7,4) in m, and Point 2 is at(x2,y2) = (13,13) in m. The Electric Field is constant, with a magnitude of 80 V/m, and is directed parallel to the +x-axis. The potential at point 1 is 1100 V.
a. Compute the potential at point2.
b. Compute the work required to move a negative charge of Q = -470μC from point 1 to point 2.
