SHMHard
Question
A mass of 0.2 kg is attached to the lower end of a mass less spring of force-constant 20 N/M, the upper end of which is fixed to a rigid support. Which of the following statement is are/true ?
Options
A.In equilibrium the spring will be stretched by 1 cm.
B.If the mass is raised till the spring is outstretched state and then released, it will down by 2cm before moving upwards.
C.The frequency of oscillation will be nearly 5 Hz.
D.If the system is taken to the moon, the frequency of oscillation will be the same as on the earth.
Solution
At equilibrium mg = kx0
⇒ x0 =
= 0.01 m = 1 cm
Amplitude of SHM = 1cm
Frequency =
⇒ x0 =
= 0.01 m = 1 cmAmplitude of SHM = 1cm
Frequency =
