Two particles of mass m each are tied at the ends of a light string of length 2a. Thesystem is kept on a frictionless horizontal surface with the string held tight so that eachmass is at a distance a from the centre P (as shown in the figure).Now, the mid-point of the string is pulled vertically upwards with a small but constantforce F. As a result, the particles move towards each other on the surface. The magnitudeof acceleration, when the separation between them becomes 2x, is
