Question

frequency of oscillation i 5hearsdz how how many osscilation will complete in 1 minuet​
explain step by ​stp

Answer 1

Explanation:

When the lift is at rest, the frequency of oscillation of simple pendulum is

$v = \frac{1}{2\pi} \: \sqrt{ \frac{9}{p} }$

When the lift falls freely, then effective value of acceleration due to gravity is

${g}^{ |} \: = g - a = g - g = 0$

$v = 2\pi \sqrt{ \frac{0}{l = 0} }$
