Question

Q1. Equipotential maps can be thought of as topographical maps. A positive test charge is like a skier in the terrain, and will always move "downhill". What do you look for on a topographical map to find the steepest region? The shallowest? How can you tell when the slope is nearly constant? Which way will a positive test charge move if tossed dowrn somewhere on each map? Where will the force be the strongest? The weakest? Q2. Suppose you are handed a map which has both positive and negative equipotentials. You are told that a test charge has been placed at a particular location where the potential is y = 0 volts. Does the test charge feel a force?

Explanation / Answer

In equipotential map, the region having maximum density of filed lines will have strong estimated field. And the charge will move from the high density field line region to low density field line region.
