Question

Please explain thank you.

Electric Fields are related to the Coulomb force (i.e. like charges repel, opposite charges attract). Field lines tell you the direction of the force on a positive "test" charge. The electric force is related to the electric field by the equation F = qE, where q is your test charge. If you drew an arrow indicating the force on this "test" charge at all points in space you would get a drawing of the electric field lines. You can try this out with the applet at: (The picture above is a screen shot of the applet. Note that the "test" charges here are negative! This is not the convention that most physicists use, but you get the idea.) The spacing of a contour (or equipotential lines) is an indicator of how rapidly energy will change as an object crosses them. Match up the following three topographic maps with the three side views of the hills they might represent

Explanation / Answer

A-2 ... There is unoiform drop in voltage

B- 1 initially the change is low reflected by low slope in B and it eventually rises.

C-3 initially the change is high reflected by high slope in C and it eventually decreases.
