Draw lines of forces and equipotential lines surrounding for a single point charge

Draw lines of forces and equipotential lines surrounding a dipole (AB)

What do you mean by equipotential line? State the properties of equipotential lines. Show that electric lines of force and equipotential lines are mutually perpendicular to each other.

Describe schematically the equipotential surfaces corrsponsing to a single positive charge at the origin Use the concept that the equipotential surface is always normal to the direction of electric field.
