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

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

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.

What is the shape of equipotential surfaces for a uniform electric field?

What is not true for equipotential surface for a uniform electric field?

Draw an equipotential surface in a uniform electric field?

The top of the atmosphere is at about 400 KV with respect to the surface of the earth, corresponding to an electric field that decreases with altitude. Near the surface of the earth, the field is about 100 Vm^-1 . Why then do we not get an electric shock as we step out of hte house into the open? Assume the house to be steel cage so there is no field inside?

Following are two statements about the relationship between the electric field an electric potential. If the electric potential is constant in a region, then the electric field is zero in that region. Giving example, predict whether these statements are correct or false.
