What is the moment of inertia of solid sphere of density rho and radius R about its diameter ?

Answer»

`(105)/(176)R^(2)rho`
`(105)/(176)R^(2)rho`
`(176)/(105)R^(2)rho`
`(186)/(105)R^(2)rho`

SOLUTION :`I=(2)/(5)MR^(2)=(2)/(5)[(4)/(3)piR^(2)rho]R^(2)=(8)/(15)piR^(5)rho`
`I=(176)/(105)R^(5)rho""(because pi=(22)/(7))`
