To calculate the gravitational potential at any point inside a solid sphere, why do we need to separately integrate gravitational field from infinity to radius and then from radius to the point? Why can''t we do it like for a point outside or on the surface where we just need to integrate from infinity to the point because all the stacked hollow

No headers. A solid sphere is just lots of hollow spheres nested together. Therefore, the field at an external point is just the same as if all the mass were concentrated at the centre, and the field at an internal point (text{P}) is the same is if all the mass interior to (text{P}), namely (M_r), were concentrated at the centre, the mass exterior to (text{P}) not contributing at

Gravitational field intensity inside a hollow sphere

However, if you deal with a solid sphere, instead of a ''point'' inside the sphere, you have to deal with a concentric region inside the sphere. No matter how you define that concentric region, so long as the center resides at the main sphere''s center, the net pull of gravity towards the outer perimeter remains a net force of zero.

Gravitation: Potential: Newton''s Shell Theorem

Thus the potential inside the sphere is independent of position--that is it is constant in r. Since F = we can infer that the shell exerts no force on the particle inside it. For a solid sphere this means that for a particle, the only gravitational force it feels will be due to the matter closer to center of the sphere (below it).

Gravity Force Inside a Spherical Shell

The net gravitational force on a point mass inside a spherical shell of mass is identically zero! Physically, this is a very important result because any spherically symmetric mass distribution outside the position of the test mass m can be build up as a series of such shells. This proves that the force from any spherically symmetric mass
