Equipotential surfaces

Nature of equipotential surface for a point charge is

Can two equipotential surfaces cut each other?

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

Write two properties of equipotential surfaces.

What is angle between electric field and equipotential surface?

Define an equipotential surface. Draw equipotential surfaces : (i) in the case of single point charge and (ii) in a constant electric field in Z -direction. Why the equpotential surfaces about a single charge are not equidistant ? (iii) Can electric field exist tangential to an equipotential surface ? Given reason.

(i) Two isolated metal spheres A and B have radii R and 2R respectively and same charge q. Find which of the two spheres have (a) greater capacitance (b) greater energy density just outside the surface of the spheres. (ii) (a) Show that the equipotential surfaces are closed together in the regions of strong field and far apart in the region of weak field. Draw equipotential surfaces for an electric dipole. (b) Concentric equipotential surfaces due to a charged body placed at the centre are shown. Identify the polarity of the charge and draw the electric field lines due to it.
