Question
A block [b] is attached to two unstretched springs
and
with spring constants
and 4 k, respectively (see figure I). The other ends are attached to identical supports
and
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
(figure II) and released. The block returns and moves a maximum distance
towards wall 2. Displacements
and
are measured with respect to the equilibrium position of the block B. The ratio
is

- 4
- 2
The correct answer is: 

As springs and supports (
and
) are having negligible mass. Whenever springs pull the massless supports, springs will be in natural length. At maximum compression, velocity of
will be zero

And by energy conservation
