Asmall marble attached to a massless thread is hung from a horizontal support. when the marble is pulled back a small distance from equilibrium and released, it swings in simple harmonic motion with a frequency .
what is the frequency of the pendulum if the length of the thread is increased by a factor of 4,4, but the marble is still released in the same way?
a,
b.

Ответ:
f' = 2 f
Explanation:
The frequency of the pendulum that swings in simple harmonic motion is given by :
Where
l is the length of pendulum
g is the acceleration due to gravity
If the length of the thread is increased by a factor of 4, such that, l' = 4 l, let f' is the new frequency such that,
f' = 2 f
So, the new frequency of the pendulum will become 2 time of initial frequency. Hence, the correct option is (b) "2f"
