Question

How will the time period of a pendulum change if the length will four times and amplitude will half?

Answer 1

Answer:

Time period of second pendulum is given by   T=2π  

g

l

​

 

​

 

⟹ T∝  

l

​

 

Thus if the length if second pendulum is increased by 4 times, its time period gets increased by 2 times.

Explanation:

Answer 2

Answer:

The period of a simple pendulum is not dependent on its amplitude but dependent on its length L and the acceleration due to gravity g. If you increase its amplitude to 4 times of its original amplitude the period might change only very slightly but the change is unpredictable.
