Two objects attract each other with gravitational force of 25 newtons from a given distances. If the distances between the two objects is reduced by a factor of 5, what is the changed force of attraction between them?

According to the gravitational force law, force existing between two objects is proportional to the mass of the two objects and inversely proportional to the square of the distance between them. When the distance is reduced to a factor of five, the force of attraction increases to 25 times.
