1. A ring , a disk and a sphere all of same mass and radius, with moments of inertia Ir, Id, Is respectively about their axes, roll down without slipping on an inclined plane from a given height. If the time taken for the ring, disk and sphere to reach the bottom of the plane are tr, td and ts respectively, then
1)tr<td<ts
2)tr=td=ts
3)tr>td>ts
4)tr>td=ts
5)tr>td<ts
. torque=moment of inertia*angular acceleration
I took the torque acting on the objects to be the same theefore moment of inertia to be indirectly proportional to angular acc.
Ir>Id>Is
therefore:
tr<td<ts
If anyone show where I went wrong, it'll be of great help.
