Physics · Oscillations
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 at its equilibrium position, another mass m is gently placed upon it. The new amplitude of oscillation will be:
- 1A√M√(M - m)
- 2A√(M - m)M
- 3A√M√(M + m)✓
- 4A√(M + m)M
Correct answer
A√M√(M + m)
