Question

what will be the time period of a simple pendulum if pendulum is taken where the value of'g' is 4 times that the surface of the Earth ?​

Answer 1

Answer:

Time period of a simple pendulum=2$\pi$$\sqrt\frac{l}{g}$ ,[where l is the length of the pendulum]

Now,when value of g becomes 4 times,

Time period of pendulum=2$\pi$$\sqrt\frac{l}{4g}$

⇒$\pi$$\sqrt\frac{l}{g}$ is the new time period of simple pendulum after g becomes 4 times
