two particles each of mass m are tied at the ends of a light string of length 2a. the whole system is kept on a frictionless horizontal surface with a string held tight so that each mass is 'a' distance away frm the centre P Now the midpoint of the string is pulled vertically upwards with a small but constant force F. As a result, the particals move towards each other on the surface. Find the magnitude of acceleration, when the separation betweenthem becomes 2x.
