A horizontal platform moves up and down simple harmonically, the total vertical movement being 10 cm what is the shortest period permissible, if object resting on the platform are to remain in contact with it throughout the motion.? Take `g=980cms^(-2)`

A horizontal platform vibrate up and down with a simple harmonic motion of amplitude 20 c.m. At what frequency will an object kept on the platform remain just in contact with the platform ? Take g = 9.81 m//s^(2) .

A shelf moves vertically with simple harmonic motion whose time period of motion is T seconds. Find the maximum amplitude that it can have so that objects resting on the shelf may always remain in contact with it.

A horizontal platform with an object placed on it is executing S.H.M. in the vertical direction. The amplitude of oscillation is 2.5 cm. If the object is not detached from the platform, then the least period of these oscillations will be, (g=10m//s^(2))

A horizontal platform with an object placed on it is executing SHM in the vertical direction . The amplitude of oscillation is 2.5 cm what must be the least period of these oscillations so that the object is not detached ?

A horizontal platform with an object palced on it executes simple hormonic motion in the vertical direction. The amplitude of oscillation is 3.92xx10^(-3) m. What should be the least period of these oscillations , so that the object is not detached from the platform ?

A horizontal platform with a small object placed on it executes a linear SHM in the vertical direction. The amplitude of oscillation is 40 cm. What should be the least period of these oscillation, so that the object is not detached from the platform ? [ Use g=10 m//s^(2)]

A large horizontal surface moves up and down in SHM with an amplitude of 1 cm . If a mass of 10 kg (which is placed on the surface) is to remain continually in contact with it, the maximum frequency of S.H.M. will be

A horizontal platform with a small block of mass 1 kg kept on it performs vertical SHM of amplitude 1 cm. The block does not lose contact with the platform anywhere. The minimum possible time period of the platform
