Question

Three galaxies are taking a walk on the wild side for several billion y years. As a result, galaxies B and C merge violently under the jealous eyes of the spacefaring races of galaxy A. Galaxy A has a mass of 4m, galaxies B and C has masses of 2m each. Initially the distances between them are d, - 2Mp (1 Megaparsec 3,086 X 10 m), d; -1 Mp. After the collision the distance between the galaxy A and the merged galaxies is d 4Mp. -3.086 X 10 m), d-1 Mp. After the collision the distance between d, BC acting on r ro between the gravitational forces before and after the collision acting on Galaxy A? What is the ratio grav
