I just have a couple of questions concerning electric field.
Is the electric field in the direction of path zero at every point from a to b in a straight line?
What about along the equipotential line joining a-b?
Is the electric field in the direction perpendicular to the path zero in the straight line joining a-b?
What about the equipotential line joining a-b?
The Attempt at a Solution
The main thing that is confusing me is what is this "path" the question refers to? Would that be the path going from one equipotential line to the next?
Thanks in advance!
