Step 1

**Given information:**

Radius of the iron disk = R

Mass of the disk = m

Distance of each child from the centre initially = R

Mass of each child = (2/5) m

Initial time taken by the disk to make one rotation (T) = 5 s

Let the initial, moment of inertia and angular velocity = I_{1}, ω_{1}

Let the final, moment of inertia and angular velocity = I_{2}, ω_{2}

Step 2

Hence the initial moment of inertia is given by:

Step 3

Now, according to law of conservation of angular momen...
