If the same figure tau is applied in each of these cases ran

If the same figure tau is applied in each of these cases. rank them in decreasing order of the resting angle acceleration. rank from largest to smallest angular acceleration to rank items as overlap them.

Solution

According to the given problem,

Assume that the three masses are point masses, so that there is moment of inertia required to spin a mass about its own centre line.

= I* where = angular accelaration, and I momentum of inertia,

as the order of momentum inertia is given as

A < B < C

as the torque is constant and order of angular accelration is

A > B > C
