Question

What tangential speed must the bob have so that it moves in a horizontal circle with the string always making an angle from verticle?

Part A
(Figure 1)A bob of mass m is suspended from a fixed point
with a massless string of length L (i.e., it is a pendulum). You
are to investigate the motion in which the string moves in a
cone with half-angle 0.
What tangential speed, v, must the bob have so that it moves in a horizontal circle with the string always making an angle 0 from the vertical?
Express your answer in terms of some or all of the variables m, L, and 0, as well as the free-fall acceleration g.
