Two particle execute S.H.M along the same line at the same frequency they move in opposite direction ya the mean position the phase difference will be

So, wt = π/3The same constraint happens for x2, except that is moving in the other direction. So the closest value is wt+? = 2π/3.To find out the phase difference ? between them, substitute π/3 for wt ion the equation wt+? = 2π/3,wt+? = 2π/3π/3+? = 2π/3or, ? =2π/3 - π/3= π/3From the above observation we conclude that, the phase difference between the two particles will be π/3

wt+? = 2π/3,wt+? = 2π/3π/3+? = 2π/3or, ? =2π/3 - π/3= π/
