A bicycle si resting on its stand in the east-west direction and rear wheel is rotating at `100` revolution per minute. Length of each spoke is `30 cm`, and vertical component of earth's magnetism is `1.5 xx 10^(-5)` tesla. If the emf induced in the spokes is `3 pi xx 10^(-6)V`, the angle of dip will be :

A bicycle is resting on its stand in the east - west direction and the rear wheel is rotated at an angular speed of 100 revolutions per minute. If the length of each spoke is 30.0 cm and the horizontal comonet of the earth's magnetic field is 2.0 X 10^(-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.
