A block of mass $m$ is released at rest from a point P of a rough circular path of radius $r$ as shown in the figure. There is a spring of stiffness $k$ at the other end of the path. (acceleration due to gravity $= g$). The maximum spring deflection is
- A. independent of $r$
- B. more than $\sqrt{2mgr/k}$
- C. equal to $\sqrt{2mgr/k}$
- D. less than $\sqrt{2mgr/k}$
