Sorry for any errors in posting, this is my first thread. Any help would be greatly appreciated!
Homework Statement
a.)On the contour map that is attached, find the magnitude of the electric field at each point A, B, and C.
b.)Calculate the work done in moving a 1C positive charge from point A to point B.
Homework Equations
For a.) E=dV/dx Change in potential between bounding equipotential lines/length of the line between bounding equipotentials.
For b.) W=qΔV
The Attempt at a Solution
For a.) I can find the electric fields at points A and B, but I am not sure how to find point C. Since it is surrounded by the 180, does this mean the magnitude of the electric field at point C is zero? Also, I am not sure the direction of the electric field at point C. I know it is from high potential to low potential.
For b.) Using W=qΔV, I have W=(1C)(180-170). I feel as though I am way off. Does it matter that the lines are not uniform?
