A solid sphere and a spherical shell roll down an incline from same height the ratio of times taken by them is
View answer and explanation
Correct option: A
21/25\sqrt {21/25}
Option A (21/25\sqrt {21/25}) is correct because the ratio of times is inversely proportional to the square root of the acceleration, which depends on the moment of inertia.

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.
