The centre of mass of an inhomogeneous s...

The centre of mass of an inhomogeneous sphere is at a distance of 0.3 R from its geometrical centre. R is the radius of the sphere. Find the maximum inclination `(theta)` of an incline plane on which this sphere can be placed in equilibrium. Assume that friction is large enough to prevent slipping.
