A block (B) is attached to two unstretched S₁ and S₂ with spring constants k and 4 k , respectively (see figure I). The other ends are attached to identical supports M₁ and M₂ 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 II) and released. The block returns and moves a maximum distance y to
Options
- A4
- B2
- C1 2
- D1 4
Correct answer
C. 1 2
Step-by-step solution
From energy conservation, aligned 1 2 k x^2 & = 1 2 (4 k) y^2 y x & = 1 2 aligned correct option is (c).
