Answer :
The length of the string is 12.35 cm if the 126 g ball is tied to a string. It is pulled to an angle of 8.00 ∘ and released to swing as a pendulum.
What is simple harmonic motion?
Simple Harmonic Motion is described as a motion in which the restoring force is proportionate to the body's displacement from its mean position.
As we know, the period T of a simple pendulum of length L is:
[tex]\rm T = 2\pi \sqrt {\dfrac{L}{g}}[/tex]
T = 12/17 = 0.705 sec
[tex]\rm 0.705 = 2\pi \sqrt {\dfrac{L}{9.81}}[/tex]
Squaring both sides and solving:
We get:
L = 0.123 m or
L = 12.35 cm
Thus, the length of the string is 12.35 cm if the 126 g ball is tied to a string. It is pulled to an angle of 8.00 ∘ and released to swing as a pendulum.
