A person normally weighing 60 kg stands ...

A person normally weighing `60 kg` stands on a platform which oscillates up and down harmonically at a frequency `2.0 sec^(-1)` and an amplitude `5.0 cm` . If a machine on the platform gives the person's weight against time deduce the maximum and minimum reading it will shown, `Take g = 10 m//sec^(2)`.

Text Solution

Verified by Experts

Maximum reading `=(mg+momega^(2)a)//g kgf,`
Minimum reading `=(mg-momega^(2)a)//gkgf.`
