two blocks, of masses m_1 and m_2, are connected to each other and to a central post by cords as shown in the figure . They rotate about the post at a frequency f (revolutions per second) on a frictionless horizontal surface at distances r_1 and r_2 from the post. Derive an algebraic expression for the tension in the segment of the cord from the post to the block of mass m_1.Express your answer in terms of some or all of the variables m_1, m_2, f , r_1, and r_2.
