A particle is moving with a constant linear velocity 5 cm/s, on the circumference of circle of radius 10 cm. The centripetal acceleration of the particle will be

A

0

B

`2.5" cm/s"^2`

C

`2" cm/s"^2`

D

`0.5" cm/s"^2`

Verified by Experts

The correct Answer is:

B

Centripetal acceleration `= (v^2)/( r) = ((5)^2)/( 10) = 2.5" cm/s"^2`
