The centripetal acceleration formula is given as:
Correct answer: D. None of these options are correct
- A. V/r
- B. r/V
- C. ma
- D. None of these options are correct
Explanation
The formulae for centripetal acceleration are: a = vω a = rω2 a = v2/r where v is the linear speed, r is the radius and ω is angular velocity.

About Angular and Linear Quantities
Rotational motion relates angular displacement, angular velocity and angular acceleration to linear displacement, tangential velocity and tangential acceleration through the radius. Questions use radians, v equals r omega and tangential acceleration, while distinguishing tangential velocity from centripetal acceleration and angular quantities from their linear counterparts.
