JEE AdvancedPhysicsSimple Harmonic MotionMCQ+3 / −1
As shown in the figures, a uniform rod OO' of length l is hinged at the point O and held in place vertically between two walls using two massless springs of same spring constant. The springs are connected at the midpoint and at the top-end (O') of the rod, as shown in Fig. 1 and the rod is made to oscillate by a small angular displacement. The frequency of oscillation of the rod is f₁. On the other hand, if both the springs are connected at the midpoint of the rod, as shown in Fig. 2 and the rod is made to oscillate by a small angular displacement, then the frequency of oscillation is f₂. Ignoring gravity and assuming motion only in the plane of the diagram, the value of f1f2\frac{f_1}{f_2}f2​f1​​ is: JEE Advanced 2025 Paper 2 Online Physics - Simple Harmonic Motion Question 2 English
