ELECTROSTATICS2

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 : If a charge particle enters into a uniform electric field, then its path must be straight line. and STATEMENT -2 : Electrostatic force on a positive charge particle is always in the direction of electric field.

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.

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.

STATEMENT-1 : In any condition the electric field inside a conductor is always zero. STATEMENT-2 : Under electrostatic condition, conductor is a equipotential volume. STATEMENT-3 : Electric field just outside a conducting surface is ( sigma)/(2 in_(0))

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: PbS can be separated from ZnS by electrostatic separation method. and STATEMENT-2: PbS is a good conductor and Zns is a poor conductor of electricity.
