Question

Q. Explain what happens to the period of oscillation, if the point of suspension of the simple pendulum.
i. Moves vertically upwards with an acceleration *a*
ii. Moves downwards vertically with acceleration less than the acceleration due to gravity.
iii. Falls freely under gravity.(3)​

Answer 1

Answer:

The well-known formula for the time period T of a simple pendulum of length L

I will write the equation as…

To make this logic obvious, if L = 1 then T = K×√1 = K×1

So if we double the length, L = 2 so T = K×√2

This means that if L is doubled, the time period gets multiplied by √2

Answer 2

Answer:

(I)

Explanation:

moves vertically upward with an acceleration
