1. Suppose there are two galaxies orbiting one another in space. The force between them can be calculated using Newton's Universal Law of Gravitation. I recommend writing down the equation and using our shortcut to complete these questions. a) Imagine that the mass of one of the two orbiting galaxies magically becomes twenty-two times smaller. Would the gravitational force between the two orbiting galaxies become stronger or would it become weaker with this change to one of them? How many times stronger or weaker would the gravitational force between those two orbiting galaxies become when this change occurs? b) Imagine that the distance between the two orbiting galaxies suddenly becomes seven times bigger. Would the gravitational force between the two orbiting galaxies become stronger or would it become weaker with this change to them? When this change occurs, how many times stronger or weaker would the gravitational force between those two orbiting galaxies become? c) Suppose one of the two orbiting galaxies masses now instantly becomes three times bigger. In this case, would the gravitational force between the two orbiting galaxies become stronger or would it become weaker when this change occurs? Determine how many times stronger or weaker would the gravitational force between those two orbiting galaxies become when this new change happens
