Chapter 1 Electric Charges and Fields Assertion reason
These questions of two statements each, printed as Assertion and Reason. While answering these Questions you are required to choose any one of the following four responses.
(A) If both Assertion & Reason are true & the Reason is a correct explanation of the Assertion.
(B) If both Assertion and Reason are true but Reason is not a correct explanation of the Assertion.
(C) If Assertion is true but the Reason is false.
(D) If Assertion & Reason both are false.
Q.1 Assertion: Farad is too big a unit of capacity.
Reason: Capacity of earth- which is the largest sphere is in microfarad.
(1) A (2) B (3) C (4) D
Answer: 1
Q.2 Assertion : When charges are shared between any two bodies, some charge is lost, and some loss of energy does occur.
Reason : Some energy disappears in the form of heat, sparking etc.
(1) A (2) B (3) C (4) D
Answer: 4
Q.3 Assertion : The whole charge of a body can be transferred to another body.
Reason : Charge can not be transferred partially.
(1) A (2) B (3) C (4) D
Answer: 3
Q.4 Assertion : Capacity of a parallel plate condenser increases on introducing a conducting or insulating slab between the plates.
Reason : In both the cases, electric field intensity between the plates reduces.
(1) A (2) B (3) C (4) D
Answer: 1
Q.5 Assertion : In a series combination of capacitors, charge on each capacitor is same.
Reason : In such a combination, charge can move only along one route.
(1) A (2) B (3) C (4) D
Answer :1
Q.6 Assertion : Increasing the charge on the plates of a capacitor means increasing the capacitance.
Reason : Because Q = CV Þ Q µ C.
(1) A (2) B (3) C (4) D
Answer: 4
Q.7 Assertion : A dielectric slab is inserted between the plates of an isolated charged capacitor. The charge on the capacitor will remain the same.
Reason : Charge on a isolated system is conserved.
(1) A (2) B (3) C (4) D
Answer: 1
Q.8 Assertion : The capacitance of a capacitor depends on the shape, size and geometrical placing of the conductors and its medium between them.
Reason : When a charge q passes through a battery of emf E from the negative terminal to an positive terminal, an amount qE of work is done by the battery.
(1) A (2) B (3) C (4) D
Answer: 2
