Question

the lengths of two pendulums are 110 cm and 27.5 cm . calculate the ratio of their time periods

Answer 1

hiii friend
here is your answer
$time = 2\pi \sqrt{ \frac{l}{g} }$
I case
$time = 2\pi \times \sqrt{ \frac{110}{g} }$
II case
$time = 2\pi \times \sqrt{ \frac{27.5}{g} }$
so, the ratio of the time be⬇
$= \frac{ \sqrt{110} }{ \sqrt{27.5} } \\ = \frac{10.48}{5.22} \\ = \frac{2}{1} \\ = 2:1$
this will be the final answer.
