Answer:
The length of the pendulum is 14.13 meters.
Step-by-step explanation:
The length of a pendulum is given by the formula,
, where T is the times period and L is the length of the pendulum.
Now, given that T = 2.4π seconds.
So, from the above equation, we get,
![2.4\pi = 2\pi \sqrt{\frac{L}{g} }](https://tex.z-dn.net/?f=2.4%5Cpi%20%20%3D%202%5Cpi%20%20%5Csqrt%7B%5Cfrac%7BL%7D%7Bg%7D%20%7D)
⇒ ![\sqrt{\frac{L}{g}} = 1.2](https://tex.z-dn.net/?f=%5Csqrt%7B%5Cfrac%7BL%7D%7Bg%7D%7D%20%3D%201.2)
⇒
{We have the value of g as 9.81 m/sec²}
⇒ L = 1.44 × 9.81 = 14.13 meters. (Approx.)
Therefore, the length of the pendulum is 14.13 meters. (Answer)
