The question is that there are two masses m₁ and m₂ kept at a distance of r meters from each other. Then to find the force of attraction between the two masses.
Newtons' law of gravitation says that Force
We need to know the value of m2 also to find the force. Substitute the values in the given expression to find the answer.
The force depends on the value of mass of the second body. If the mass m₂ = 50 kg also, then the force = 4.16875 * 10⁻¹° Newtons.
