Statement A: If a particle is outside a uniform spherical shell or solid sphere with a spherically symmetric internal mass distribution, the sphere attracts the particle.
Statement B: If a particle is inside a uniform spherical shell, the gravitational force on the particle is zero.
Statement C: If a particle is inside a uniform solid sphere, the gravitational force on the particle is zero.
In light of above statements choose the correct option.
Solution:
Statements A and B are correct (shell theorem). Inside a uniform solid sphere, the gravitational force is non-zero (except at the center) and varies linearly with distance from the center.
