In electrostatic condition electric lines of force become perpendicular to metal surface. Why?

Text Solution

Verified by Experts

For charge to remain at rest on the surface of metal, electric field must be perpendicular to the surface of metal, or else a tangential component will move the charge, which is against electrostatics

When is an electric line of force straight ?

When is an electric line of force straight ?

Assertion: Not net charge can stay in volume of metallic object when the same is in electrostatic condition. Net charge of metallic object appears on its outer surface. Reason: When a metallic object attains electrostatic condition then electric field intensity becomes zero everywhere inside the volume of the metallic object.

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.

Why no two electric lines of force can interscet each other ?

If electric field is uniform, then the electric lines of forces are :
