An object of mass m1 = 0.125 kg undergoes uniform circular motion and is connected by a massless string through a hole in a frictionless table to a large object of mass m2 = 0.225 kg. What is the centripetal force acting on the object in terms of its mass and circular motion parameters?
a) F = m1 × m2
b) F = m1 + m2
c) F = m1 × m2 × g
d) F = m1 × v² / r
