Transcribed Image Text:If you followed a line on such a map, you
would remain at a constant elevation. Thus, these
contour lines are lines of equal elevation. Now
suppose you have a similar plot showing lines of
equal electrical potential. Briefly describe how you
could use this plot to calculate the magnitude of the
average electric field over a small distance on this
plot. (Do not use calculus terms like integral or
derivative in your answer.)
Expert Solution

Step 1
Given,
Each line here represents the equipotential surface.
we know that,
Change in electric potential is given by,
dV = -E .dr
E = -dV/dr
