1. The problem statement, all variables and given/known data The moment of inertia of a sphere rotating about an axis through its center is (2/5)MR^2, where M is the mass and R is the radius of the sphere. What is the moment of inertia of the sphere about an axis on the edge of the sphere? a. 0.4 MR^2 b. 1.4 MR^2 c. 0.9 MR^2 d. 0.6 MR^2 2. Relevant equations I = (2/5)MR^2 3. The attempt at a solution I think it's just a. since nothing besides the equation is given.
