Explain— Electric field lines cut the equipotential surface normally.

Equipotential surfaces

Define electric field lines.

The electric field lines pass through an equipotential surface _______. [Fill in the blank]

Show that electric field intensity is normal to equipotential surface.

Can two equipotential surfaces intersect?

Explain why, for any charge configuration the equipotential surface through a point is normal to the electric field at that point. Draw a sketch of equipotential surfaces due to a single charge (-q), depicting the electric field lines due to the charge.

"Electric field lines always meet the surface of a conductor normally" - justify the statement.

Depict the equipotential surfaces due to an electric dipoel.

The electric field strength at a point in an electric field is zero. Is the electric potential also zero at that point? Answer with reason.

The electric field at a point is
