Two objects with a gravitational force of 5000 n are moved apart 3 times the original distance. what is the new gravitational attraction?

Gravitational force between two objects will depends on mass and distance between the two objects

It is given by the formula as

Now here we can say that it depends inversely on square of distance between two masses

now if force is 5000 N when two masses are at distance "r" from each other

so it is given as

similarly we can say that if distance is increased by 3 times then we will have

now we will find the ratio of two forces

so now the new force will be given as

it about 600 mph from what i calculated

f=ma newton's second law 7x8=56n
