The moment of inertia of a sphere with uniform density about an axis through its center is
Question:
(a) Show that the moment of inertia about a diameter of a uniform spherical shell of inner radius Rio outer radius R and density p is 1 = p(πm/15)(R5/2 – R5/1'). (Hint: Form the shell by superposition of a sphere of density p and a smaller sphere of density -p.)
(b) Check the given data by using them to calculate the mass of the earth.
(c) Use the given data to calculate the earth's moment of inertia in terms of MR.
