Teo particles move along a straight line with same frequency and amplitude in differnent direction. If one particle reaches hailf of its amplitude, what is the phase difference between the two particles?

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