Question

A boy moves on a circular distance of radius R starting from a point A he moves to a point B which is on the other end of the diameter AB.the ratio of the distance travelled to the displacement made by him is​

Answer 1

Answer:

Distance=2πr Displacement=2r

Explanation:

Distance/Displacement= 2πr/2r

on cancellation (2&r)

We get, π:1

Answer 2

Given:

A boy moves on a circular distance of radius R starting from a point A he moves to a point B which is on the other end of the diameter AB.

To find:

Ratio of distance and displacement?

Calculation:

• Distance is defined is the total path length travelled by an object.

In this case, distance will be :

$distance \: (d) = \dfrac{2\pi R}{2} = \pi R$

• Displacement is defined as the shortest length between the starting and stopping point of an object.

In this case , placement will be equal to the diameter.

$displacement \: (s) = 2R$

So, required ratio is :

$\boxed{d : s = \pi R : 2R = \pi : 2}$
