Equipotential surfaces in an electric field.

The dashed lines in the diagram represent cross sections of equipotential surfaces drawn in 1-V increments.

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

b) What is the work W_AD in J done by the electric force to move a 1-rm C charge from A to D?

c) The magnitude of the electric field at point C is
1)greater than the magnitude of the electric field at point B.
2)less than the magnitude of the electric field at point B.
3)equal to the magnitude of the electric field at point B.
4)unknown because the value of the electric potential at point C is unknown.
