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?

  1. Please show some work of your own. E-Field = -(Voltage change)/(separation)
    when the separation is measured perpendicular to equipotential surfaces.

    In your case, V changes by 70 V in 2.0 meters.

    In this case, the field in in the -x direction

  2. exactly what drwls said.

    Electric field =
    -(change in charge)/(change in position)

    So in this case in particular, you have:
    - (190V-120V)/(5.00m-3.00m)
    = - (70V)/(2.00m)
    = -35V/m or -35 N/C

    *V/m = N/C*
