A particle moves with a constant speed v along a circular path of radius r and completes the circle in time T. What is the acceleration of the particle?

A

`( 2 pi r)/( T)`

B

`(2 pi v )/( T)`

C

`( pi r ^(2))/( T)`

D

`( pi r ^(2))/( T ^(2))`

Text Solution

Verified by Experts

The correct Answer is:
B
`a = (v ^(2))/( r ) implies a = omega v implies a = ( 2 pi v )/(T).`
