Oscillation is a type of periodic motion which repeats itself to and from about a point which is called mean position. The period of a Pendulum can be described as a ratio between the length and gravity as,
[tex]T = 2\pi \sqrt{\frac{L}{g}}[/tex]
Here,
L = length
g = Gravity
If we rearrange to find the length we have that,
[tex]L = \frac{T^2g}{4\pi^2}[/tex]
Our period is 2s and the gravity is 9.8m/s^2, then,
[tex]L = \frac{(2)^2(9.8)}{4\pi^2}[/tex]
[tex]L = 0.9929m[/tex]
The simple required length of the pendulum must be 0.9929m
