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

Options

A. 0.5 Hz
B. 1.5 Hz
C. 5 Hz
D. 10 Hz

Answer

C

Explanation

Since, `a_(max)=g`
`implies omega^(2)A=g implies (2pif)^(2)A=g`
`implies f^(2)=(10)/(4pi^(2)xx0.01)=25implies f=5Hz`.
