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.

b . is zero.

Explanation:

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.
