This is a multiple choice answer as classified in NCERT Exemplar

X (t+T)=acos [ $α (t + T)$ ]²

= acos [ $α t^{2} + α T^{2} + 2 α t T$ ]

So it is not periodic.

So it is oscillatory but not periodic

In the given figure, a mass M is attached to a horizontal spring which is fixed on one side to a rigid support. The spring constant of the spring is k. The mass oscillates on a frictionless surface with time period T and amplitude A. When the mass is in equilibrium position, as shown in the figure, another mass m is gently fixed upon it. New amplitude of oscillation will be:
