Question
In the figure below, the dotted lines show the equipotential lines of electric fields. (A charge moving along a line of equal potential would have a constant electric potential energy.) A charged object is moved directly from point A to point B. The charge on the object is+ mu C. How does the amount of work needed to move this charge compare for these three cases? Most work required in 1. Most work required in II. Most work required in III. I and II require the same amount of work but less than III. All three would require the same amount of work. 18. 1 low does the magnitude of the electric field at B compare for these three cases? For case III what is the direction of the electric force exerted by the field on the + 1 mu C charged object when at A and when at B? left at A and left at B right at A and right at B left at A and right at B right at A and left at B no electric force at either.Explanation / Answer
a) left at A and left at B
bcoz particle traveled from low potential to high potential
at point A 20V
at mid between A nad B is 30 V
at point B 40 v
