In the figure shown, the pulley, strings and springs are mass less. The block is moved to right by a distance `x_(0)` from the position where the two springs are relaxed. The block is released from this position.

(a) Find the acceleration of the block immediately after it is released.
(b) Find tension `(T_(0))` in the support holding the pulley to the wall, immediately after the block is released.
Assume no friction .

Answer

(a) `(4k_(1)k_(2)x_(0))/((k_(1) + k_(2))M)`
(b) `(4k_(1)k_(2)x_(0))/(k_(1) + k_(2))`
