A positive charge is moved from one point to another point along an equipotential surface. The work required to move the charge:______.
a. is positive.
b. is zero.
c. is negative.
d. depends on the magnitude of the potential.
e. depends on the sign of the potential.

An Equipotential surface is the one that has electric potential same throughout the surface. The formula for work done in an electric field is given by

dW= qdV

Now, in an Equipotential surface dV= 0.

Hence the work done in moving a charge from one place to the other in an electric field is zero.
