The uniform solid sphere shown in the figure has a spherical hole in it. Find the position of its centre of mass.

Text Solution

Verified by Experts

The correct Answer is:
`I=(57)/(140)MR^(2)`

`rho=(M)/((4//3)piR^(3)-(4//3)pi(R//2)^(3))`
`I=(2)/(5)MR^(2)-((2)/(5)M_(2)((R)/(2))^(2)+M_(2)((R)/(2))^(2))`
`,I=(57)/(140)MR^(2)`
