Objects 1 and 2 attract each other with a gravitational force of 72.0 units. if the mass of object 1 is one-fourth the original value and the mass of object 2 is tripled and the distance separating objects 1 and 2 is halved, then the new gravitational force will be units.

New gravitational force, F' = 216 units

Explanation:

Given that,

Gravitational force between object 1 and 2, F = 72 N

The gravitational force between two objects is given by :

............(1)

If the mass of object 1,

If the distance between objects is halved,

Let new gravitational force is F'. It is changed to :

F' = 216 units

So, the  new gravitational force will be 216 units.
