Answer the following question.
What is a conical pendulum?
उत्तर
In a simple pendulum, a mass m is suspended by a string of length l and moves along an arc of a vertical circle. If the mass instead revolves in a horizontal circle and the string which makes a constant angle with the vertical describes a cone whose vertex is the fixed point O, then the mass string system is called a conical pendulum.
