The earth is a homogeneous sphere of mass M and radius R. There is another spherical planet of mass M and radius R whose density changes with distance r from the centre as `p=p_(0)r.` (a) Find the ratio of acceleration due to gravity on the surface of the earth and that on the surface of the planet. (b) Find `p_(0).`
