JEE MainPhysicsSimple Harmonic MotionMCQ+4 / −1
In the given figure, a mass M is attached to a horizontal spring which is fixed on one side to a rigid support. The spring constant of the spring is k. The mass oscillates on a frictionless surface with time period T and amplitude A. When the mass is in equilibrium position, as shown in the figure, another mass m is gently fixed upon it. The new amplitude of oscillations will be : JEE Main 2021 (Online) 24th February Morning Shift Physics - Simple Harmonic Motion Question 104 English
