Determine the gravitational field

Reference no: EM13275227

A planet of total mass M and radius R has a non-uniform density such that p(r) = po (1-r/R), where po is the density at the center. Determine the gravitational field g(r) at a point r ? R inside the planet. Hint: recall that the volume element for a sphere is dV=4?r^2dr.
