The figure below shows a "conical pendulum", in which the bob (the small object at the lower end of the cord) moves in a horizontal circle at constant speed. (The cord sweeps out a cone as the bob rotates.) The bob has a mass of 0.035 kg, the string has length L = 0.56 m and negligible mass, and the bob follows a circular path of circumference 0.92 m. (a) What is the tension in the string? _________ N (b) What is the period of the motion? _________ s

  tension in the cord is made up of weight mg, and centripetalforce directed outward. Add those as vectors to get tension. Period=2PIsqrt(l/g)
