Question

If a pendulum is oscillating 30 times in 15 sec, then calculate the time period.​

Answer 1

We have,

[tex]\large\boxed{T = \frac{1}{ f}} [/tex]

Here,

f = frequency = $\frac{15}{30}$ = $\large{ \frac{1}{2}} Hz$

Therefore,

T = $\dfrac{1}{\frac{1}{2}}$

$\Large\mathcal{\boxed{T = 2 sec}}}$
