A block (B) is attached to two unstretched springs S and Sa with spring constants k and 4 k, respectively (see figure I). The other ends are attached to identical supports M, and Ma not attached to the walls. The springs and supports have negligible mass. There is no friction anywhere. The block B is displaced towards wall 1 by a small distance x (figure 1) and released. The block returns and moves a maximum distance y towards wall 2. Displacements x and y are measured with respect to the equilibrium position of the block B. The ratiois Ma S M S M S S (a) 4 (b) 2 (c) d)
