What the ratio of masses? (b) the two stars of a double star system have concentric circular orbits of radii ri and r2. what is the ratio of their masses? hint: the orbital speed v in a circular orbit of radius r is v rw, where w is the angular velocity.

Explanation:

As we know that in dual mass system we have two masses moves in circular path such that they moves about their common center of mass

The mutual force on them will be centripetal force for both

also we know that

since angular speed for both will be same

the force required to move the cart is divided by three or 33.33 n.

grav forces affect all objects magnetic forces affect magnetic objects and electric currents
