The acceleration of an object moving with speed v in a circle of radius r is

A

`(u^(2))/(r )` towards the centre

B

`(u)/(r )` way from the centre

C

`(u)/(r^(2))` way from the centre

D

`(r )/(u^(2))` towards the centre

Text Solution

Verified by Experts

The correct Answer is:
A
Cendripetal offorce acting on an object in unifomcircuaar motion is,
`f=(mv^(2))/(r)`
or accekeration is `(f)/(m)=(v^(2))/(r)` towards the centre.
