An object is moving in a circle of radius 100 m with a constant speed of `31.4 m//s` . What is its average speed for one complete revolution

A

Zero

B

`31.4 ms^(-1)`

C

`3.14 ms^(-1)`

D

`sqrt(2)xx31.4 ms^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
B
As the speed is constant throughout the circular motion, therefore its average speed is equal to instantaneous speed.
