Question

A 6.00 kg pendulum bob is placed on a 10.0 m long string and pulled back 5.00°. What is the period of the pendulum when it is released?3.84 s8.03 s6.35 s1.27 s

Answer 1

As we know that time period for a pendulum is,

`\begin{gathered} T=2\pi\sqrt[\placeholder{⬚}]{(l)/(g)} \\ Here, \\ l=10m \\ g=9.8\text{ m/s}^2 \\ So, \\ T=2*3.14\sqrt[\placeholder{⬚}]{(10)/(9.8)}=6.343s \\ \end{gathered}`

So 3rd option is correct option.
