PhysicsSystems of Particles and Rotational MotionMHT CET

The moment of inertia of a solid sphere of mass M and radius R about its diameter is . Its M.I. about parallel axis passing through a point at a distance (R/2) from its centre is

Answer: (C)

Solution

I=\frac{2}{5}MR^2+M\left(\frac{R}{2}\right)^2=\frac{8}{20}MR^2+\frac{5}{20}MR^2=\frac{13}{20}MR^2;
