Question

A particle is describing the circular path of radius 20 m in every 2 s. The average angular speed of the particle during 4 s is ?

(A) 20 t rad s-1 B 4 n rad s-1
( f) u rad s (D) 2n rad s-1
​

Answer 1

The correct option- (C) π rad s-1

Explanation:-

ω=$\frac{Angle \: Described }{Time \: Taken } \\ = \frac{2\pi}{2} = \pi \: rad \: per \: s$

Answer 2

Hey mate! your answer is ll rad/s.

ω= angle described/time taken

= 2ll/2 rad per second

= ll rad per second
