The figure below shows a "conical pendulum", in which the bob (thesmall object at the lower end of the cord) moves in a horizontalcircle at constant speed. (The cord sweeps out a cone as the bobrotates.) The bob has a mass of 0.030kg, the string has length L = 0.90 m and negligible mass,and the bob follows a circular path of circumference 0.88 m.
(a) What is the tension in the string?
1 N

(b) What is the period of the motion?
2 s
