Explanation:

Answer :

frequency of conical pendulum is the number of revolution per unit time.

Si unit : hertz

The time period of conical pendulum is

Tsin=mrw²

Tcos=mg

tan=rw²/g

tan=r/h=r/lcosthetha

h=Lcos

$t = 2\pi \frac{ \sqrt{r} }{lcos \alpha }$

$n = \frac{1}{2\pi} \sqrt{ \frac{gcos \alpha }{r} }$

$n \alpha \sqrt{g}$

n inversely proportional to 1/rootr

where g is the acceleration due to gravity in that's placed

hence proved......
