JEE AdvancedPhysicsSimple Harmonic MotionMCQ+3 / −1
A uniform rod of length L and mass M is pivoted at the centre. Its two ends are attached to two springs of equal spring constants kkk. The springs are fixed to rigid supports as shown in the figure, and the rod is free to oscillate in the horizontal plane. The rod is gently pushed through a small angle θ\thetaθ in one direction and released. The frequency of oscillation is IIT-JEE 2009 Paper 2 Offline Physics - Simple Harmonic Motion Question 8 English
