The work required to carry a particle with a charge of 6.0 c from a 5.0-v equipotential surface to a 6.0-v equipotential surface and back again to the 5.0-v surface is zero.
What are the properties of equipotential surface?
The electric field present around the surface is perpendicular to an equipotential surface.
Two equipotential surface can never met or intersect.
The direction is always from high potential to low potential.
If there is an isolated point charge, then the equipotential surface is a sphere.
Equipotential points are those points in an electric field that has same electric potential. If these points are connected by any line or curve, it is said to be equipotential line and the surface on which it lies is the equipotential surface.
The work done between two points in an equipotential surface is always zero. It is calculated in the following manner:
If any charge moves from point Va to Vb in an equipotential surface, then work done in moving charge
W= q0 (Va- Vb)
As (Va- Vb) = 0 so the total work is equal to zero.
