Question

A toy car of mass m is having two similar rubber ribbons attached to it as shown in the figure. The force constant of each rubber ribbon is k and surface is frictionless. The car is displaced from mean position by x cm and released. At the mean position the ribbons are unreformed. Vibration period is

Options

A.
B.
C.
D.

Solution


Rubber ribbon can exert only tension not compression so at a time only one is effective.
T =
