A vertical tree is broken by the wind at a height of 6 m from its foot and its top touches the ground at a distance of 8 m from the foot of the tree. Calculate the distance between the top of the tree before breaking and the point at which of the tree touches the ground after break.

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 center P (as shown in 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 :
