Express your answers for the questions below in terms of the gravitational con- stant g, the masses, and the distance l. assume that the stars move on circular orbits. (a) what is the rotational period t of an equal-mass (m = m = m) double star of sepa- ration l? [10 points) (b) what is the rotational period t of an unequal-mass ( m m ) double star of separation l? (15 points) (c) what is the rotational period t of an equal-mass (m1 = m = m3 = m) triple star, where the stars are located at the corners of an equilateral triangle (side l)?
