A solid sphere of mass M and radius R is divided into two unequal parts. The first part has a mass of (7M)/(8) and is converted into a uniform disc of radius 2R. The second part is converted into a uniform solid sphere. Let I_(1) be the moment of inertia of the disc about its axis and I_(2) be the moment of inertia of the new sphere about its axis. The ratio (I_(1))/(I_(2)) is equal to __________ .
A solid sphere of mass M and radius R is divided into two unequal parts. The first parts has a mass of (7M)/8 and is converted into a uniform disc of radius 2R. The second part is converted into a uniform solid sphere.
