A certain transverse sinusoidal wave of wavelength 20 cm is moving in the positive x direction. The transverse velocity of the particle at x=0 as a function of time is shown. The amplitude of the motion is:

A. `(5)/(pi)cm`
B. `(pi)/(2)cm`
C. `(10)/(pi)cm`
D. `2pi cm`

A. `(5)/(pi)cm`
B. `(pi)/(2)cm`
C. `(10)/(pi)cm`
D. `2pi cm`
Correct Answer – c
`V_(max)=Aomega=5 implies A(2pi)/(4)=5`
`implies A=(10)/(pi)cm`
