Consider the situation shown in figure, A spring of spring constant $400\,N / m$ is attached at one end to a wedge fixed rigidly with the horizontal part. A $40\,g$ mass is released from rest while situated at a height $5\,cm$ the curved track. The minimum deformation in the spring is nearly equal to (take $g =10\,m / s ^2$ )
