?Show that the velocity of a star orbiting its galaxy in a circular orbit is inversely
Chapter 11, Problem 69(choose chapter or problem)
Show that the velocity of a star orbiting its galaxy in a circular orbit is inversely proportional to the square root of its orbital radius, assuming the mass of the stars inside its orbit acts like a single mass at the center of the galaxy. You may use an equation from a previous chapter to support your conclusion, but you must justify its use and define all terms used.
