From a uniform disc of radius R, an equilateral triangle of side sqrt(3)R is cut as shown in the figure. The new position of centre of mass is :

The figure shows a disc of radius 3R from which a circular hole of radius R is cut as shown in the figure. The distance of the centre of mass of the remaining object from the point O is

A circular of radius R has mass 9m . A hole of radius (R)/(3) is cut from it as shown in figure. The moment of inertia of the remaining part about an axis passing through centre 0 of the disc and perpendicular of the plane of disc is xmR^(2) .Find value of x

A uniform disc of radius R has a round disc of radius R/3 cut as shown in Fig. The mass of the remaining (shaded) portion of the disc equals M. Find the moment of inertia of such a disc relative to the axis passing through geometrical centre of original disc and perpendicular to the plane of the disc.

A uniform disc of mass m & radius R is pivoted at its centre O with its plane vertical as shown in figure A circular portion of disc of radius (R)/(2) is removed from it. Then choose the correct option(s)

A semicircle disc of mass M and radius R is held on a rough horizontal surface as shown in figure. The centre of mass C of the disc is at a distance of (4R)/(3pi) from the point O . Now the disc is released from this position so that it starts rolling without slipping. Find (a) The angular acceleration of the disc at the moment it is relased from the given position. (b) The minimum co-efficient of fricition between the disc and ground so that it can roll without slipping.

Two thin discs each of mass M and radius r metre are attached to form a rigid body as shown in figure. The rotational inertia of this body about an axis perpendicular to the plane of disc B and passing through its centre is
