# A conical pendulum is formed by attaching a ball of mass \( m \) to a string of length \( L \), then allowing the ball to move in a horizontal circle of radius \( R \).

A conical pendulum is formed by attaching a ball of mass \( m \) to a string of length \( L \), then allowing the ball to move in a horizontal circle of radius \( R \).

**Part a)** Find an expression for the tension in the string in terms of \( m \), \( L \), and \( R \). *(3 points)*

**Part b)** Derive an expression for the period of the pendulum in terms of \( m \), \( L \), and \( R \). *(4 points)*
