The drawing shows a graph of a set of equipotential surfaces in cross section. The grid lines are 2.0 cm apart. Determine the magnitude and direction of the electric field at position D.
Specify whether the electric field points toward the top or the bottom of the drawing.
The Attempt at a Solution
I am uncertain how to solve for this problem, ΔV is usually between 2 variables, final - initial. Do I repeat this process for each field above point D?
