Satellite Motion: Speed & Period
Three asteroids A1, A2 and A3 are orbiting around a star having a radius of r. Asteroid A1 has a mass of M, A2 has a mass of 3M and A3 has a mass of 4M. Calculate the force experienced by A2 and A3 if the force on A1 is 15000 N. It is known that A1 completes the orbit in 290 minutes.
