Consider two point masses of mass \( m_{1} \& m_{2} \) kept at a distance \( r \) from each other. The magnitude of
\( \mathrm{P} \) gravitational force between them is denoted by \( \mathrm{F} \),

W then if the mass of one is doubled while that of other is halved \& their seperation is increased by a factor of 3 , then magnitude of gravitational force between them will be :-
(1) \( \mathrm{F} \)
(2) \( \frac{F}{9} \)
(3) \( \frac{4 \mathrm{~F}}{9} \)
(4) \( 9 \mathrm{~F} \)
