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. The new amplitude of oscillation will be :

A

`A sqrt((M - m)/(M))`

B

`A sqrt((M)/(M+m))`

C

`A sqrt((M+m)/(M))`

D

`A sqrt( (M)/(M - m))`
