question_answer1) Directions (Q. No. 1 - 8): In the following questions, A statement of Assertion (A) is followed by a statement of Reason (R). Mark the correct choice as. Assertion (A): Electric field is always normal to equipotential surfaces and along the direction of decreasing order of potential. Reason (R): Negative gradient of electric potential is electric field. [CBSE SQP 2020-21]
question_answer2) Assertion (A): Electric field inside a hollow conducting sphere is zero. Reason (R): Charge is present on the surface of conductor.
question_answer3) Assertion (A): Work done in moving a charge between any two points in a uniform electric field is independent of the path followed by the charge between these two points. Reason (R): Electrostatic forces are non- conservative.
question_answer4) Assertion (A): Electric potential and electric potential energy are two different quantities. Reason (R): For a test charge Q and a point charge Q, the electric potential energy becomes equal to the potential.
question_answer5) Assertion (A): When the distance between the parallel plates of a parallel plate capacitor is halved and the dielectric constant of the dielectric used is made three times, then the capacitance becomes three times. Reason (R): Capacitance does not depend on the nature of material.
question_answer6) Assertion (A): Circuit containing capacitors should be handled very carefully even when the power is off. Reason (R): The capacitors may break down at any time.
question_answer7) Assertion (A): Capacity of a conductor is independent on the amount of charge on it. Reason (R): Capacitance depends on the dielectric constant of surrounding medium, shape and size of the conductor.
question_answer8) Assertion (A): Two parallel metal plates having charge +Q and -Q are facing at a distance between them. The plates are now immersed in kerosene oil and the electric potential between the plates decreases. Reason (R): Dielectric constant of kerosene oil is less than 1.
