Question

a boy is sitting on a swing if another boy sits along with him without disturbing the motion how will the time period change​

Answer 1

Answer:

there will be no change in time period

you can try this at home

tie a mass to a string like a pendulum and oscillate it

try using different masses

you can see same time in every case

Answer 2

The time period will not change.

Explanation:

A swinging boy can be considered a simple pendulum.

Time period :

Time period of the pendulum is

$T=2\pi\sqrt{\dfrac{l}{g}}$

Where, l = length of pendulum

g = acceleration due to gravity

T = time period

Length of the pendulum is equal to the distance from point of suspension to center of gravity of the oscillation of body.

Time period is depend upon the length of the pendulum from point of suspension to center of gravity.

A boy is sitting on a swing then the time period is

$T = 2\pi\sqrt{\dfrac{l}{g}}$

If the another boy sits along with him without distubing the motion

Then the time period will be same because both are sits on swing so the center of gravity will be same.

Hence, The time period will not change.
