A ring of mass M and radius R is rotating about its axis with angular velocity omega. Two identical bodies each o mass m are now gently attached at the two ends of a diameter of the ring. Because of this, the kinetic energy loss willbe

Answer»

`(m(M+2m))/(M)OMEGA^(2)R^(2)`
`(Mm)/((M+m))omega^(2)R^(2)`
`(Mm)/((M+2m))omega^(2)R^(2)`
`((M+m)M)/((M+2m))omega^(2)R^(2)`
