Solution:If an object moves in a circular path with a uniform speed, then the object is said to be in Circular motion. Velocity is defined as the displacement of an object in unit interval time.
Velocity (v) = displacement / time.
For a circular motion, Velocity (v)
= circumference of a circular path/ time
As, Circumference of the circle = 2 π r
Where r = radius of the circular path.
∴ v = 2π𝑟/t
Therefore, the velocity of an object moving in circular path of radius r is
given by v = = 2π𝑟/t
