SHMHard
Question
Two particles execute S.H.M. of same amplitude and frequency along the same straight line from same mean position. They cross one another without collision, when going in opposite directions, each time their displacement is half of their amplitude. The phase-difference between them is
Options
A.0o
B.120o
C.180o
D.135o
Solution
Consider SHM as projection of uniform circular motion.
From figure the phase difference between two particles is 120o.
From figure the phase difference between two particles is 120o.
