Draw an equipotential surface in a uniform electric field.

Define equipotential surface.

Read the statement carefully and write 'Yes' for correct statements and 'No' for wrong statements : An equipotential surface is a uniform field region.

State whether the electric dipole moment is a scalar or a vector quantity. Draw the equipotential surfaces due to an electric dipole and locate the points, where the potential due to dipole is zero.

Prove that when an electric dipole is placed in a uniform electric field, potential energy U is given by U=-p*E .

Correct the following statement. An equipotential surface and line of force in an electric field are parallel to each other.
