Which formula can be used to find the centripetal acceleration of an orbiting object?

ac = StartFraction the square root of v over T EndFraction.
ac = StartFraction v Superscript 2 Baseline over T EndFraction
ac = StartFraction v Superscript 2 Baseline over r EndFraction.
ac = StartFraction the square root of v over r EndFraction.

ac = v² / r

Reason: Centripetal acceleration for circular motion is a_c = v²/r (equivalently a_c = ω²r, and using period T: a_c = (2πr/T)² = 4π²r/T²).
