A metallic ring of mass 2 kg and radius 1m with a uniform metallic spoke of same mass 2kg and lengt 1 m is rotated about its axis with angular velocity 1 rev sec in a perpendicular uniform magnetic field B of magnitude 10T as shown if figure If the central end of the spoke is connected to the rim of the whee through a resistor R of magnetiude 2 as shown The resistor does not rotate its one end is always a the center of the ring and other end is always in contact with the ring A force F as shown is needed t maintain constant angular velocity of the spoke then F is equal to The ring and the spoke has zem resistance 2 110 A 10 N F BIL Ragna a que spoke 43 67 Himmens B1m 15 TM COUHIA B 20 N and an dad del art spoke K R vafra art spoke fa B E ata frufe Ru R a mi yo f m g n c z a as qpja vu fay fuargar da Fe X xxx Fx C 50 N D 30 N 2 kg
