As shown in the figure, a homogeneous rod with a length of L = 1 m and a mass of m = 0.2 kg is fixed so that it can rotate in the middle. Two springs with a constant k = 30 N / m are connected at the 2 ends of the rod. The other ends of the springs are fixed and the springs are unstretched. the rod is rotated from the equilibrium position about theta angle and released. The angular frequency of the rod is how many rad / s. g = 10 k m, k
