    A small object of mass(m) is suspended from a string of length (L). The object revolves with constant speed (v) in a horizontal circle of radius (r),(Because the sring sweeps out the surface of a cone, the system is known as a conical pendulum).Find that the expression for V (speed) is :

    v= square root of (L g sin(theta) tan (theta)

    What are the forces acting on the object? What is the momentum vector of the object at any point in the circle?
