From a uniform wire, two circular loops are made. One loop P of radius r and the other Q of radius nr. If the moment of inertia of Q about an axis passing through its center and perpendicular to its plane is 8 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):
