Answer:
zero
Explanation:
For the box remaining at rest, the total acceleration on the box must be zero. Since force F = m*a, the force F must also be zero.
Answer:
b)
Explanation:
Rotational inertia of the sphere: 
Rotational inertia of hollow sphere: 
Rotational inertia of flat disk: 
The largest value is 2/3 mr², therefore, hollow sphere's inertia is largest.
