Find the elastic potential energy stored in each spring shown in figure, when the block is in equilibrium. Also find the time period of vertical oscillation of the block.

Text Solution

Verified by Experts

The correct Answer is:
`(M^(2)g^(2))/(2k), (M^(2)g^(2))/(4k)` and `(M^(2)g^(2))/(6k)` from above, time period `= 2pisqrt((11m)/(6k))`
