Two identical spherical balls of mass M and radius R each are stuck on two ends of a rod of length 2R and mass M (see figure). The moment of inertia of the system about the axis passing perpendicularly through the centre of the rod is :

A person of mass M is assuming that his centre of mass moves by a distance ℓ(ℓ sitting on a swing of length L and swinging with an angular amplitude θ0. If the person stands up when the swing passes through its lowest point the work done by him
