A circular disc of radius R and thickness R/6 has moment of inertia  about an axis passing through its center and perpendicular to its plane. It is melted and re casted in to a solid sphere. The moment of inertia of the sphere about its diameter as axis of rotation is.

A ring of mass M and radius r  is melted and then molded in to a sphere then the moment of inertia of the sphere will be.....

In 

One solid sphere A and another hollow sphere B are of the same mass and same outer radii. The moment of inertia about their diameters are respectively I_A and I_B such that....

If 

One circular rig and one circular disc both are having the same mass and radius. The ratio of their moment of inertia about the axes passing through their centers and perpendicular to their planes, will be,.....

A circular plate of uniform thickness has a diameter of 56 . A circular portion of diameter 42 cm . is removed from +ve  x edge of the plate. Find the position of center of mass of the remaining portion with respect to center of mass of whole plate

If f(x) =  x then 

From a uniform circular disc of radius R, a circular disc of radius R/6 and having center at a distance +R/2 from the ceater of the disc is removed. Determine the center of mass of remaining portion of the disc.

Four particles A,B,C and D of masses m,2 m,3 m and 5 m respectively are placed at corners of a square of side x as shown in figure find the coordinate of center of mass take A. at origin of x-y plane

If  and 

Consider a two-particle system with the particles having masses M₁, and m₂. If the first particle is pushed towards the center of mass through a distance d, by what distance should the second particle be moved so as to keep the center of mass at the same position?
