Draw a neat labelled diagram of conical pendulum. State the expression for its periodic time in terms of length.

Explanation

### Step-by-Step Solution for the Conical Pendulum

**Step 1: Draw the Diagram**
- Start by drawing a vertical line to represent the string of the pendulum. At the end of this line, draw a small circle to represent the bob of the pendulum.
- From the point where the string is attached, draw a horizontal circle to represent the path of the bob.
- Label the length of the string as \( L \), the angle between the string and the vertical as \( \theta \), and the radius of the circular path as \( R \).
