Which of the following statements is correct about the gravitational force inside a hollow spherical shell?
The net gravitational force inside a uniform hollow spherical shell is zero due to symmetry, making option 2 correct. As per NCERT, applying relevant law/formula with correct units and sign convention leads to It is zero everywhere inside. This satisfies dimensional consistency and physical conditions given, so option B is scientifically correct.
