A circular disc of radius `20cm` is cut from one edge of a larger circular disc of radius `50cm`. The shift of centre of mass is

A circular disc of radius R is removed from a bigger circular disc of radius 2R such that the circumference of the discs coincoid . The centre of mass of the new disc is alphaR from the centre of the bigger disc . the value of alpha is

A circular disc of radius (R)/(4) is cut from a uniform circular disc of radius R. The centre of cut portion is at a distance of (R)/(2) from the centre of the disc from which it is removed. Calculate the centre of mass of remaining portion of the disc.

A circular disc of radius R is removed from a bigger circular disc of radius 2R such that the cirucmferences of the discs coincide. The centre of mass of the new disc is alpha/R from the center of the bigger disc. The value of alpha is

A circular disc of radius R is removed from a bigger circular disc of radius 2 R such that the circumferences of the discs coincide. The center of mass of new disc is alpha R from the center of the bigger disc. The value of alpha is

A circular disc of radius R is removed from a bigger circular disc of radius 2R such that the circumference of the disc coincide. the centre of the mass of the new disc from the centre of bigger disc is is

A circular disc of radius R is removed from a bigger circular dise of radius such that the circumferences of the discs coincide. The centre of mass of the new disc is alphaR from the centre of the bigger disc. The value of a is:

A circular hole of radius R//2 is cut from a circular disc of radius R . The disc lies in the xy -plane and its centre coincides with the origin. If the remaining mass of the disc is M , then a. determine the initial mass of the disc and b. determine its moment of inertia about the z -axis.
