The electric field in a region of space is ex = -1000x v/m, || 22 47. the electric potential in a region of space is v = 200/ 2x + y , is the electric field strength midway between the electrodes? ||2 200y 2 v, where x and y are in meters. what are the strength and direction of the electric field at 1x, y2 = 12.0 m, 2.0 m2? give the direction as an angle cw or ccw (specify which) from the positive x-axis. xf=30cm?
