Web5 de nov. de 2024 · We can also use this formula to calculate the mass of a sphere if we know its density and radius. By rearranging the previous formula: \small m = \cfrac {4} … WebIf the gravitational field vector is independent of the radial distance within a sphere, find the function describing the mass density ρ ( r) of the sphere. I uses the divergence of g: ∇ ⋅ g → = 4 π G ρ g = − G M r ^ r 2 so I can take the divergence which is (using spherical) ∇ ⋅ g → = − 4 π G M So ρ = − M This does not make sense to me at all.
