What is Dimensional Formula of Centripetal acceleration ?

Centripetal acceleration is the acceleration directed towards the centre of curvature of the path of a body which is moving along that path with a constant speed.

Mathematically,
Centripetal acceleration = (Velocity)² / radius.

Dimensional Formula of Velocity = M⁰L¹T^-1
Dimensional Formula of Radius = M⁰L¹T⁰

Putting these values in above equation we get,
Dimensional Formula of Centripetal acceleration = M⁰L¹T^-2
SI unit of Centripetal acceleration is ms^-2
