Previous Question: Which of the following statements about the instantaneous axis (passing through the centre of mass) is correct? (A) It is vertical for both the cases (a) and (b). (B) It is verticle for case (a); and is at 45° to the x-z plane and lies in the plane of the disc for case (b) (C) It is horizontal ofr case (a); and is at 45° to the x - z plane and is normal to the plane of the disc for case (b). (D) It is vertical of case (a); and is at 45° to the x - z plane and is normal to the plane of the disc for case (b). Next Question: A current carrying infinitely long wire is kept along the diameter of a circular wire loop,without touching it. The correct statement (s) is (are) : (A) the emf induced in the loop is zero if the current is constant. (B) The emf induced in the loop is finite if the current is constant. (C) The emf induced in the loop is zero if the current decreases at a steady rate. (D) Theemf induced in the loop is finite if the current decreases at a steady rate.
