physics
The electric potential at x = 3.0 m is 120 V, and the electric potential at x = 5.0 m is 190 V. What is the electric field in this region, assuming it's constant?

physics (electric field)
The drawing shows the potential at five points on a set of axes. Each of the four outer points is 6.2 x 10-4 m from the point at the origin. From the data shown, find the magnitude of the electric field in the vicinity of the origin.
