A particle is moving along a circular path of radius 5 m with uniform speed of `5 m//s`. What will be time taken by the particle in half revolution?

Options

A. `pi//2 s`
B. `2pi s`
C. `pi s`
D. `3 pi //2 s`

Answer

C

Explanation

`v=romega, " "thereforeomega=(v)/(r)=(5)/(5)=1`
`T=(2pi)/(omega)=2pi " " T'=(T)/(2)=(2pi)/(2)=pis`
