Vedclass · Answer

(A) The universal law of gravitation,expressed as $F = G \frac{m_1 m_2}{r^2}$,describes the gravitational force between two point masses.For extended objects,this formula is strictly valid only when the objects are spherical and their mass distribution is uniform (spherically symmetric).In such cases,the entire mass of the sphere can be considered to be concentrated at its center,allowing the distance $r$ to be measured between the centers of the two spheres.

The equation $F = G \frac{m_1 m_2}{r^2}$ is valid only for:
