Question

anushka was sitting on a swing. She asked atharv to hep her to swing . athrav pulled the swing 50cm towards him and then left it. how much distance will the swing cover to complete one oscillation?
​

Answer 1

Answer:

Let the swinging be a simple pendulum,

So the time period of the simple pendulum is:

T=2π

g

L

Where L is the length,

Since length of the simple pendulum is equal to the distance from the point of suspension to CG of the oscellting body,

When the girl stands up the distance of CG from the point of suspension will decrease.

Therefore time period of the oscillation also decreases.
