Question

Using the figure:

A) What is the work done by the electric force to move a 1 C charge from A to B?

B) What is the work done by the electric force to move a 1 C charge from A to D?

C)

The magnitude of the electric field at point C is:

greater than the magnitude of the electric field at point B. less than the magnitude of the electric field at point B. equal to the magnitude of the electric field at point B. unknown because the value of the electric potential at point C is unknown. Figure 2 V 1 V 0 -2 V 3

Explanation / Answer

A) Work=change in V * Q

so W=0*1=0J

B)

W=1*1=1J

C)

Ans: greater than the magnitude of the electric field at point B

Since the diagram shows equal potential differences between adjacent surfaces, equal amounts of work are done to move a particular charge from one surface to the next adjacent one. It follows then that if the equipotential are closer together, the electric force does the same amount of work in a smaller displacement than if the equipotential were farther apart. Therefore, the electric force, as well as the corresponding electric field, has a larger magnitude than point B.
