A bicycle is resting on its stand in the east-west direction and the rear wheel is rotated at an angular speed of `50` revolutions per minute.If the length of each spoke is `30.0 cm` and the horizontal component of the earth's magnetic field is `4xx10^(-5) T`,find the `emf` induced between the axis and the outer end of a spoke Neglect centripetal force acting on the free electrons of the spoke.
