A wheel has mass of the rim 1 kg, having 50 spokes each of mass 5g. The radius of the wheel is 40 cm. The moment of inertia is

A wheel with a certain number of spokes is rotated in plane normal to earth's magnetic field so the an e.m.f. is induced between the axle and rim of the wheel. Keeping all other things same, number of spokes is changed. How is the e.m.f. affected ?

The spokes of a wheel are made of metal and their lengths are of one metre. On rotating the wheel about its own axis in a uniform magnetic field of 5xx10^(-5) tesla normal to the plane of the wheel, a potential difference of 3.14 mV is generated between the rim and the axis. The rotational velocity of the wheel is-
