Question
The diagrams below show portions of four different regions with electric fields. The dashed lines represent cross-sections of flat electric equipotential surfaces or sheets. The potentials for several sheets in each region are labeled. The distance from the leftmost equipotential surface and the rightmost one is 20 cm in each case.
Rank the magnitudes of the electric fields at each point marked x, A – H:
Greatest 1._____ 2._____ 3._____ 4._____ 5._____ 6._____ 7._____ 8._____ Least
Region 1 Region 2 20 cm 20 cm Ix 30 V 70 V 110V 30V 60V 90V Region 3 -20 cm > Region 4 20 cm--> 30 V 20 V 10V 900 V 930V 960 VExplanation / Answer
A=B
C=D=G=H
E=F
When electric potential is represented as vertical lines and the lines are equally spaced, then electric field is uniform. The smallest spacing indicates the greatest electric potential.
