1.	A mass of 0.2 kg is attached to the lower end of a massless spring of force constant 200 N/m, the upper end of which is fixed to a rigid support. Which of the following statements is/are true? In equilibrium, the spring will be stretched by 1 cm.
Answer» If the mass is raised till the SPRING becomes unstretched and then released, it will go down by 2 cm before moving upwards. The frequency of OSCILLATION will be nearly 5 HZ. If the SYSTEM is taken to the moon, the frequency of oscillation will be the same as that on the earth. Answer :A::B::C::D
