### Question

From a uniform wire, two circular loops are made (i) P of radius r and (ii) Q of radius nr. If the moment of inertia of loop Q about an axis passing through its center and perpendicular to its plane is 125 times that of P about a similar axis, the value of n is (diameter of the wire is very much smaller than r or nr)
