Two rods each having length ll and mass m\mathrm{m} joined together at point B\mathrm{B} as shown in figure. Then find out moment of inertia about axis passing through A\mathrm{A} and perpendicular to the plane of page as shown in figure.
View answer and explanation
Correct option: D
5ml23\frac{5 m l^2}{3}
Option D (5ml23\frac{5 m l^2}{3}) is correct because it is the sum of the moments of inertia of both rods about the specified axis.

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.
