What is the moment of inertia of shell 1 along its diameter?

1. 2/3 MR²
2. 5/3 MR²
3. MR²
4. None of the above

Correct answer: 2/3 MR²

Solution

The moment of inertia of a thin spherical shell about its diameter is given by (2/3)MR², derived using the formula for rotational inertia of a spherical shell.
