b) False

Text Solution

Verified by Experts

The correct Answer is:
B
A kid of mass M stands at tehedge of the platform of a raduis R which has a moment of inertia I. S ball thrown to him and with horizontal velocity of the ball -v when we catches it.
Therefoe if we take the total bodies as a system
`mvR={1+(M+m)R^2}omega`
The moment of inerti aofkid adn ball about the axis=`(M+m)R^2`
`rarr omega=(mvR)/(1+(M+m)R^2)`
