Question
If the particle starts its motion from mean position, the phase difference between displacement and acceleration is ______.
Options
2π rad
`pi/2 rad`
`pi rad`
`pi/4 rad`
Advertisements
Solution
π rad.
Hence phase difference between displacement and velocity is 90 degrees or `pi/2` radians. ... Hence phase difference between velocity and acceleration is also `pi/2`. Phase difference between displacement and acceleration is pi radians or 180 degrees.
