Q14.35Multiple choice
A person normally weighing 50 kg stands on a massless platform which oscillates up and down harmonically at a frequency of 2.0 s–1 and an amplitude 5.0 cm. A weighing machine on the platform gives the persons weight against time.
- (a)Will there be any change in weight of the body, during the oscillation?
- (b)If answer to part (a) is yes, what will be the maximum and minimum reading in the machine and at which position?
