10:50 PM AT&T; session.masteringphysics.com C Electric Fields and Equipotential Surfaces The dashed lines in the diagram represent cross sections of equipotential surfaces drawn in 1 v Part A What is the work WA done by the electric force to move a 1 c charge from Ato B? Express your answer in joules. Submit Hints My Answers Give Up Review Part Part B What is the work W done by the electric force to move a 1 c charge from Ato D? Express your answer in joules. Submit Hints My Answers Give Up Review Part Part C The magnitude of the electric field at point Cis O greater than the magnitude of the electric field at point B. O less than the magnitude of the electric field at point B O equal to the magnitude of the electric field at point B. O unknown because the value of the electric potential at pointCis unknown.

Explanation / Answer

A) V a = Vb

dV = 0

W = q dV = q*0 = 0

b) Va = 1

Vd = 0

dV = 0 - 1 = -1

W = 1*-1 = -1 J

C)the less the distance between field lines the greater the field

so C>B

so first choice
