Q 1756112974.     According to Newton's Law of Gravitation, the

magnitude of the force F on point masses `m_1` and

`m_2` (say) is given by `|F| = (Gm_1m_2)/r^2`.

Which of the following statements about this

equation is correct?

A

This equation is not directly applicable for the gravitational force between Extended object (like the Earth) and a point mass

B

This equation can be directly applied for the gravitational force between an extended object and a point mass

C

The equations can be applied to find the gravitational force between an extended object and a point mass provided 'r' is the distance of the point mass from the geometric center of the extencled object

D

None of the above
