Figure 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 0.040 kg, the string has length L=0.90 m and negligible mass, and teh bob follows a circular path of circumfernece 0.94m. What are (a) The tension in the string and (b) the period of the motion?

Answer
