A horizontal surface moves up and down in S.H.M with an amplitude of 1 cm. If mass of 10 kg (which is placed on the surface) is to remain continuously in contact with it, the maximum frequency of S.H.M. will be
5 Hz
0.5 Hz
1.5 Hz
10 Hz
A system exhibiting S.H.M. must possess
elasticity as well as inertia
elasticity only

A body is executing SHM. When the displacements from the mean position is 4 cm and 5 cm, the corresponding velocities of the body is 10 cm/s and 8cm/s. Then the time period of the body is
A particle starts simple harmonic motion from the mean position. Its amplitude is a and time period is T. What is its displacement when its speed is half of its maximum speed ?
The acceleration of a particle performing S.H.M. is 12 cm/sec2 at a distance of 4 cm from the mean position. Its time period is
2.0 sec
3.14 sec
0.5 sec
1.0 sec
The displacement x (in metres) of a particle performing S.H.M is related to time t (in second) as :
1.0 Hz
2.0 Hz
If a simple harmonic oscillator has got a displacement of 0.02 m and acceleration equal to 2.0m/s2 at any time, the angular frequency of the oscillator is equal to
