Question

The dashed lines in the diagram represent cross sections of equipotential surfaces drawn in1

Vincrements. (Figure 1)

A. What is the work

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. The dashed lines in the diagram represent cross sections of equipotential surfaces drawn in1 V increments. (Figure 1) What is the work WAB done by the electric force to move a 1 C charge from A to B?Express your answer in joules. What is the work WAD done by the electric force to move a 1 C charge from A to D? Express your answer in joules The magnitude of the electric field at point C is The magnitude of the electric field at point C is

Explanation / Answer

a)

Vb-Va =1-1=0 V

Wab=q(Vb-Va) =1*0

Wab=0 J

b)

Vd-Va =0-1 =-1V

Wad =-q*(Vd-Va)

Wad =-1*(-1) =1 J

c)

greater than the magnitude of the electric field at point B.
