A horizontal platform with an object placed on it is executing SHM in the vertical direction . The amplitude of oscillation is `4 xx 10^(-3)` m. What must be least period of these oscillations , so that the object is not detached from the platform ? (take , `g=10 ms^(-2)`)

A

`(pi)/(25)`s

B

`(pi)/(5)`s

C

`(pi)/(10)`s

D

`(pi)/(50)`s

Text Solution

Verified by Experts

The correct Answer is:
A
`omega^(2)A=g`
`omega=sqrt((g)/(A))`
or `T = 2pi sqrt((A)/(g))=2pi sqrt((4 xx 10^(-3))/(10))=(pi)/(25)s`
