Assertion : Mass of the rod AB is `m_(1)` and of particle P is `m_(2)`. Distance between centre of rod and particle is r. Then the gravitational force between the rod and the particle is
`F=(Gm_(1)m_(2))/(r^(2))`

Reason : The relation `F=(Gm_(1)m_(2))/(r^(2))` can be applied directly only to find force between two particles.

Options

A. If both Assertin and Reason are correct and Reason is the correct explanation of Assertion
B. If both Assertion and Reason are correct but Reason is not the correct explanation of Assertion
C. If Assertion is true but Reason is false
D. If Assertion is false but Reason is true

Answer

D

Explanation

In the three cases `F=(Gm_(1)m_(2))/(r^(2))` can be applied directly
