question_answer1) Directions (Q. Nos. 1-11): In the following questions, A statement of Assertion (A) is followed by a statement of Reason (R). Mark the correct choice as. Assertion (A): Magnetic field interacts with a moving charge only. Reason (R): Moving charge produces a magnetic field.
question_answer2) Assertion (A): If an electron is not deflected when moving through a certain region of space, then the only possibility is that no magnetic field is present in that region. Reason (R): Force on electron is directly proportional to the strength of the magnetic field.
question_answer3) Assertion (A): The energy of a charged particle moving in a uniform magnetic field remains constant. Reasoning (R): Work done by the magnetic field on the charge is zero.
question_answer4) Assertion (A): An electron and a proton moving with same velocity enters a magnetic field. The force experienced by the proton is more than the force experienced by the electron. Reason (R): The mass of proton is more than the mass of the electron.
question_answer5) Assertion (A): The magnetic field at the ends of a very long current carrying solenoid is half of that at the centre. Reason (R): Magnetic field within a sufficiently long solenoid is uniform.
question_answer6) Assertion (A): The magnetic field produced by a current carrying solenoid is independent of its length and area of cross-section. Reason (R): Magnetic field within a very long solenoid is uniform.
question_answer7) Assertion (A): A direct current flowing through a metallic rod produces magnetic field both inside and outside of the rod. Reason (R): There is no flow of charge carrier inside the rod.
question_answer8) Assertion (A): In moving coil galvanometer, the coil is wound on a metallic frame. Reason (R): The metallic frame helps in making steady deflection without oscillation.
question_answer9) Assertion (A): Torque on a coil is maximum when it is suspended radially in a magnetic field. Reason (R): Torque tends to rotate a coil.
question_answer10) Assertion (A): Galvanometer to ammeter conversion takes place by connecting a low value resistance in parallel with it. Reason (R): The low value resistance increases the effective resistance and protects the galvanometer.
question_answer11) Assertion (A): Earth's magnetic field does not affect the functioning of a moving coil galvanometer. Reason (R): Earth's magnetic field is too weak.
