A small bob joins two light unstretched identical springs anchored at their far ends and arranged along a straight line, as shown in the figure

The bob is displaced in a direction perpendiular to the line of the springs by `l_(0)` (unstretched lenght ) and then released. Find acceleration of the bob just after its release. K is spring constnat of each ideal spring.

A

`(kl_(0))/(m)sqrt(2)(sqrt(2)-1)`

B

`(kl_(0))/(m)(20sqrt(2))`

C

`(kl_(0))/(m)`

D

`(2kl_(0))/(m)`

Text Solution

Verified by Experts
