In the system shown in the figure the string, springs and pulley are light. The force constant of the two springs are `k_(1) = k " and " k_(2) = 2k`. Block of mass M is pulled vertically down from its equilibrium position and released. Calculate the angular frequency of oscillation. The top surface of the block (represented by line AB) always remains horizontal.

Text Solution

Verified by Experts

The correct Answer is:
