Differeniate between equipotential surface and gaussian surface on the basis of 1) potential at any two points 2) work done to bring a charge from one point to another and 3) the line of force acting on them

Expert Answer:

 

Equipotential surface

Gaussian surface

Potential at any two points

The potential at any two points on the equipotential surface is same.

The potential at any two points on the Gaussian surface depends on the shape of the surface.

Work done

The work done in bringing a charge from one point to other on the surface is zero as both points are at same potential.

The work done in bringing a charge from one point to other on the surface can be zero or non-zero depending on the potential at the two points.

Line of force

The line of force is always perpendicular to the equipotential surface.

The line of force make different angles to the Gaussian surface depending on the shape of the area element considered.
