Physics Questionnnn!?

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 0.053 kg, the string has length L = 1.1 m and negligible mass, and the bob follows a circular path of circumference 1.2 m. What are (a) the tension in the string and (b) the period of the motion?
