Explanation:
For pendulum 1 :
Mass, m₁ = 0.1 kg
Length, l₁ = 5 m
For pendulum 2 :
Mass, m₂ = 0.9 kg
Length, l₂ = 1 m
The time period the simple pendulum is given by :
[tex]T=2\pi\sqrt{\dfrac{L}{g}}[/tex]..........(1)
And we know that frequency f is given as :
[tex]f=\dfrac{1}{T}[/tex]
[tex]f=\dfrac{1}{2\pi\sqrt{\dfrac{L}{g}}}[/tex]
From equation (1) it is clear that the time period and frequency depend on the length of the bob and acceleration due to gravity only. It is independent of its mass.
