Assertion: The whole charge of a conductor cannot be transferred to another isolated conductor.

Reason: The total transfer of charge from one to another is not possible.

Assertion : At a point in space, the electric field points towards north. In the region, surrounding this point the rate of change of potential will be zero along the east and west.

Reason : Rate of change of electric potential is along the direction of electric field.

Assertion : point charge is brought in an electric field. The field at a nearby point icnreases, whatever be the nature of the charge.

Reason : The electric field is independent of the nature of charge.

Assertion: The surface of a conductor is an equipotential surface.

Reason: Conductor allows the flow of charge.

Assertion : A charged particle free to move in an electric field always move along an electric line of force.

Reason : The electric line of force diverge from a positive charge and converge at a negative charge.

Assertion : An applied electric field will polarize the polar dielectric material.

Reason : In polar dielectrics, each molecule has a permanent dipole moment but these are randomly oriented in the absence of an externally applied electric field.

Assertion: Gravitational force between nucleus and electron in an atom is negligible to the electrical force.

Reason: The electrical force is experienced by charged particles only.
