Question

Under what condition the time period of a pendulum does not depend upon the amplitude of oscillation

Answer 1

the time period of a pendulum

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

where ,l= length of pendulum

g= gravitational force

so from the equation. the time period of pendulum doesn't depend on amplitude....

hope everything is clear

peace

Answer 2

Answer:

As long as the amplitude of the oscillations is small , the time period of a pendulum doesn't depend on the amplitude of oscillations
