Question

what is the magnitude of gravitational force between two bodies of masses m1 and m2 at separate distance r

Answer 1

Gravitational force =(G×m1×m2)/r^2
where G=6.67×10^-11 Nm^2/kg^2

Answer 2

The magnitude of gravitational force is given by
F = Gm1m2 / r^2

Where G = universal gravitational constant.
It’s value is 6.67408 × 10^-11 m^3 kg^-1 s^-2
