Two circular discs A and B of equal masses and thicknesses. But are made of metals with densities dAanddB(dA>dB). If their moments of inertia about an axis passing through the centre and normal to the circular faces be IA and IB, then.

From a given sample of uniform wire P of radius r and Q of radius nr. If the M.I. of Q about its axis is four times that of P about its axis (assuming the wire to be of diameter much smaller than either radius) the value of n is two circular loops P and Q are made
