ELECTROSTATICS-3

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.

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 : A stationary electric charge produce electrostatic field and this field exterts electrostatic force on other charge. STATEMENT-2 : Theoritically electric field is found upto infinite distance from a point charge. STATEMENT-3 : An electron is a point charge.

STATEMENT-1 : At a point electrostatic field is zero, then potential at that point may be zero . and STATEMENT-2 : Negative of the potential gradient is equal to electrostatic field.

Assertion:SiC has higher melting point than NaCl. Reason: SiC has stronger electrostatic forces of attraction.
