Two particles of mass m each are tied at the ends of a light string of length 2a The whole system is kept on a frictionless horizontal surface with the string held tight so that each mass 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 constant force F As a result the particles move towards each other on the surface The magnitude of acceleration when the separation between them becomes 2x is F a 1 2m y A F X 2m m EO 2 F P 3 EO m FX 2m a F 2m X
