String-Spring Oscillation

A small ball of mass m is hang by a string of length l and attached to a spring of stiffness k like shown below.The spring can move freely in vertical direction, but its orientation is always horizontal. The ball is in equilibrium when it forms an angle θ with horizontal.
Determine period of oscillation, T, if the ball move slightly on xy-plane!
Gravity acceleration g.

  1. got this question as well i solved it by restoring torque method.and i solved it for small oscillations .
