A particle moves on the circumference of a circle of radius r. Starting from one point particle reaches to its diametric end in time t.The magnitude of average velocity of the particle is

A

`(pir)/(t)`

B

`(pif)/(2t)`

C

`(r)/(t)`

D

`(2r)/(t)`

Text Solution

Verified by Experts

The correct Answer is:
A
We have.
`S= ((2pir)/(2))= pi` and T= t
`:. ` Average velocity` = ((S)/(T))= (pir)/(t)`
