Two particles are oscillating along two close parallel

Asked by admin @ 26/08/2021 in Physics viewed by 298 People

Two particles are oscillating along two close parallel straight lines side by side. With the same frequency and amplitude . They pass each other moving in opposite directions when their displacements is half of the amplitude. The mean positions of the two particles lie on a straight line perpendicular to the paths of the two particles. The phase difference is?

Answered by admin @ 26/08/2021

X=a sinθ
a/2=a sinθ
θ=30°,150°
∴ difference = 150°–30°=120°
= $2 \pi /3$
