A spring has a natural length of 50 cm and a force constant of 2.0 × 103 Nm–1. A body of mass 10 kg is suspended from it and the spring is stretched. If the body is pulled down to a length of 58 cm and released, it executes simple harmonic motion. What is the net force on the body when it is at its lowermost position of its oscillation? (Take g = 10 ms–2)
