An air puck of mass 0.123 kg is tied to a string and allowed to revolve in a circle of radius 1.02 m on a horizontal, frictionless table. The other end of the string passes through a hole in the center of the table and a mass of 1 kg is tied to it. The suspended mass remains in equilibrium while the puck revolves. What is the tension in the string? The acceleration due to gravity is 9.8 m/s 2 . Answer in units of N.
