Gravitational Field: Practice Problem & Solution
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.nIn light of above statements choose the correct option.
Short Solution (Best for NEET):
To solve this problem, we apply the core principles of Gravitational Field. Understanding the underlying formula is key to arriving at the correct answer below:
By shell theorems, the gravitational force inside a uniform spherical shell is zero (Statement B is correct) and outside it behaves like a point mass (Statement A is correct). Inside a solid sphere, the force is non-zero (Statement C is incorrect).
