From a given sample of uniform wire, two circular loops `P` and `Q` are made, `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

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 Q about an axis passing through its center and perpendicular to tis 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 )

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 about an axis passing through its centre 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 i or nr)

Two uniform circular loops A and B of radii r and nr are made of the same uniform wire. If moment of inertia of A about its axis is twice that of B, then find the value of n [diameter of wire is much smaller compared to radii of the loops].
