Question

Define equipotential surface draw it for a point charge and represent electric feild

Answer 1

It's an abstract surface where the potential energy is equal at every point in the surface. It could be gravitational potential energy, electric potential, etc.

Around a charge or mass, there will be infinitely many of these, nested in each other like matryoshka dolls.

Interesting side note, in two dimensions there are equipotential curves, and in four dimensions, there would be equipotential 3d spaces.

Answer 2

Explanation:

In mathematics and physics, an equipotential or isopotential refers to a region in space where every point is at the same potential. This usually refers to a scalar potential, although it can also be applied to vector potentials.
