@ss01 hey man could you plz answer this double star system ones answer..plzz!
October 21, 2013

Physics
Consider a double star system under the influence of the gravitational force between the stars. Star 1 has mass m1 = 2.42 × 1031 kg and Star 2 has mass m2 = 2.32 × 1031 kg. Assume that each star undergoes uniform circular motion about the center of mass of the ...

If it was going straight,it's weight would equal the lift force,since it is banked at an angle,the force will be split into components, horizontal lift force equals Lsin=mv^2/r,the centripetal force hence describing a radius, vertical component must equal the weight,...
