Bobs A and B of mass mA and mB (mA > mB) are connected to an inextensible light string of length / that passes through the smooth ring at C. If bob B moves as a conical pendulum such that A is suspended a distance of h from C, determine the angle θ and the speed of bob B. Neglect the size of both bobs.
