Question

The period of a conical pendulum in terms of its length (l), semi-vertical angle (θ) and acceleration due to gravity (g) is:

Options

• `1/(2pi)sqrt((l costheta)/g)`

• `1/(2pi)sqrt((l sintheta)/g)`

• `4pisqrt((lcostheta)/(4g))`

• `4pisqrt((l tantheta)/g)`

Answer 1

The time period of a conical pendulum is

`T=4pisqrt((lcostheta)/(4g))`
