STATEMENT -1 : the surface of a charged conductior is always equipotential .
STATEMENT -2 : Electic field lines are always perpendicular to the equipotential surface.

Why electric lines of force are always perpendicular to the equipotential surface ? Explain.

Show that electric field is always directed perpendicular to an equipotential surface.

Consider the three statements in context of electrostatic field lines. STATEMENT-1 : Electrostatic field lines are continuous curves in space. STATEMENTS-2 : Electrostatic field lines are always perpendicular to equipotential surface. STATEMENT-3 : A charge when released in electrostatic field moves along electrostatic field lines.
