How can we solve a conical pendulum using principles of physics?

[Equilibrium]

Guys what do you mean about a conical pendulum? And how to solve it?

 

[Tide]

A conical pendulum consists of a pendulum bob suspended by a string and set into motion such that the path of the bob is a circle in a horizontal plane. The term "conical" is used because the string traces a conical surface during one revolution.

As for solving it, I wouldn't dream of depriving you of the joy that comes with at least attempting to solve it on your own now that you know what a conical pendulum is! :)
