उत्तर

The period of a conical pendulum in terms of its length (l), semi-vertical angle (θ) and acceleration due to gravity (g) is `bbunderline(1/(2 pi) sqrt((l cos theta)/g))`.

Explanation:

For a conical pendulum, the vertical component of tension balances weight:

T cos⁡ θ = mg

Using centripetal force and angular motion relations, we get the time period:

T = `2 pi sqrt((l cos theta)/g)`

= `1/(2 pi) sqrt((l cos theta)/g)`
