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 = 0.90 m and negligible mass, and the bob follows a circular path of circumference 0.86 m.
(a) What is the tension in the string?
(b) What is the period of the motion?
I will gladly critique your work or thought process, when shown either
