Question

A particle is moving in a circle of diameter 10m . Calculate the distance travelled by the particle and it's displacement on completing one and half revolution
​

Answer 1

Answer:

Here's the answer below!!!✌️

Explanation:

The distance covered by it on completing 2 revolutions is.

Distance =2×2πr

=2πD

=2π10

=20πm.

Hope so, this answer will help you!!!

Answer 2

D = 10m

$\bf \red{ r = \dfrac{d}{2}} \\ \bf \purple{= \dfrac{10}{2} } \\ \bf \green{= 5m}$

So,

Distance in 2 revolution is 2×2πr

$\bf \blue{=2×2×3.14×5} \\ </h3><h3> \bf \green {=20×3.14} \\ </h3><h3> \bf \orange { =60.14} \\ </h3><h3> \bf \pink { =60m}$

Because the moves from one point and then comes back to that point Displacement in two rounds is 0

So,

Distance travelled = 60m

Displacement = 0m.
