Answer:
Above table shows the angular speed and revoluton period of both the particle.
we need to find n number of revolutions for particle-A and m number of revolutions for particle-B, so that
n×TA = m×TB .....................(1)
where n and m are smallest integers.
Hence , n×1 = m×1.25 or n= 5 and m = 4
Both particle-A and particl-B will meet if particle-A makes 5 revolutions and particle-B makes 4 revolutions.
Hence time for both of them meeting = 5×1 = 4×1.25 = 5 s
