Describe schematically the equipotential surfaces corresponding to - a single positive charge at the origin.

Equipotentials surfaces:

What are equipotential surfaces?

What is equipotential surface?

Describe schematically the equipotential surfaces corresponding to- a constant electric field in the z-direction.

Describe schematically the equipotential surfaces corresponding to - a field that uniformly increases in magnitude but remains in a constant (say, z) direction.

Describe schematically the equipotential surfaces corresponding to - a uniform grid consisting of long equally spaced parallel charged wires in a plane.

Draw the equipotential surfaces due to an isolated point charge.
