8. Centripetal Forces & Gravitation / Satellite Motion: Speed & Period / Problem 1

Three asteroids A₁, A₂ and A₃ are orbiting around a star having a radius of r. Asteroid A₁has 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.

ANSWERS OPTIONS

A

F_A2 = 4500 N, F_A3 = 7000 N

B

F_A2 = 20000 N, F_A3 = 15000 N

C

F_A2 = 15000 N, F_A3 = 20000 N

D

F_A2 = 7000 N, F_A3 = 4500 N
