•The period of a conical pendulum in terms of its length (l), semi vertical angle (0) and acceleration

due to gravity (g) is equal to:

(a)

$\frac{1}{2\pi} \sqrt{ \frac{l \cos0 }{g} }$

(b)

$\frac{1}{2\pi} \sqrt{ \frac{l \sin0 }{g} }$

(c)

$4\pi \sqrt{ \frac{l \cos0 }{4g} }$

(c)

$4\pi \sqrt{ \frac{l \tan0 }{g} }$
