Previous Question: A binary star consists of two starts A (mass 2.2. MS) and B (mass 1 MS), where MS is the mass of the sun. They are separated by distance d and are rotating about their center of mass, which is stationary. The ratio of the total angular momentum of the binary star to the angular momentum of star B about the center of mass is. Next Question: A 0.1 kg mass is suspended form a wire of negligible mass. The length of the wire is 1 m and its cross– sectional area is 4.9 × 10–7 m2. If the mass is pulled a little in the vertically downward direction and released, it performs simple harmonic motion of angular frequency 140 rad s–1. If the Young's modulus of the material of the wire is n × 109 Nm–2, the value of n is
