A 0.15 kg mass is placed on a vertical platform that oscillates with simple harmonic motion of angular frequency 20 rad s. At what displacement from the equilibrium position does the mass just lose contact with the platform? Take upwards as positive and g = 9.8 m s.
- 2.5 × 10 m above equilibrium
- 2.5 × 10 m below equilibrium
- 4.0 × 10 m above equilibrium
- 4.0 × 10 m below equilibrium
