Question

Two particles are executing SHM in parallel straight lines close to each other. Amplitude A and Time Period T of both the particles are equal. At time t=0, one particle is at displacement y1 = +A and other at y2 = -A/2, and they are approaching toward each other. After what time will they cross each other?​

Answer 1
