1.	A mass of 0.2kg 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?
Answer» In equilibrium, the SPRING will be stretched by `1cm`. If the mass is raised TILL the spring is unstreched state and then released, it will godown by `2cm` before moving upwards. The frequency of oscillation will be nearly `5Hz`. If the SYSTEM is taken to the MOON, the frequency of oscillation will be the same as on the earth. Answer :A::B::C::D
