Moment of inertia of a circular wire of mass MM and radius RR about is its diameter is:
View answer and explanation
Correct option: A
12MR2\frac{1}{2} {M} {R}^2
Option A (12MR2\frac{1}{2} {M} {R}^2) is correct because the moment of inertia about a diameter is half the moment of inertia about an axis perpendicular to the plane.

It is easier for a swimmer jumping into water from a height to describe a loop in the air by A uniform thin rod AB\mathrm{AB} of length L\mathrm{L} has linear mass density μ(x)=a+bxL\mu(x)=a+\frac{b x}{L}, where xx is measured from A\mathrm{A}. If the CM\mathrm{CM} of the rod lies at a distance of (712)L\left(\frac{7}{12}\right) \mathrm{L} from A\mathrm{A}, then a and b\mathrm{b} are related as : A solid metal ring and a disc of same radius and mass are rotating about their diameters with same angular frequency.
