Abstract: In this trial investigation the motion of three different diameters of spheres, all accelerating from have a rest at the same time along the centre line of a cylindrical tube crammed with a fluid, is determined as a function of time. It is exposed that if spheres are distant apart, the come around of the lower sphere induces a superior velocity for the upper sphere. For not as well large distances between the spheres, however, it is found that the velocity of the lower sphere increases considerably for decreasing distance between the spheres. The result of these two things is that the spheres attract for large distances but separate for small distances. This behavior eventually results in a stable distance which is found to be independent of the initial distance. This steady distance increases when the Deborah number increases, whereas the presence of the cylindrical tube wall reduces the stable distance.
