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`)
