What is the electrostatic potential at the surface of a silver nucleus of diameter 12.4 fermi ? Atomic number silver is 47.

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.

STATEMENT-1 : The electrostatic force is much stronger than the gravitational force. STATEMENT-2 : Electrostatic force can be attractive or repulsive. STATEMENT-3 : Electrostatic force is central force.
