Three identical spheres lie at rest along a line on a smooth horizontal surface. The separation between any two adjacent spheres is L. The first sphere is moving with a velocity u towards the second sphere at time t = 0. The coefficient of restitution for a collision between any two blocks is 1/3 The correct statement is

2n identical cubical blocks are kept in a straight line on a horizontal smooth surface. The separation between any two consecutive blocks is same. The odd numbered blocks 1, 3, 5,.....(2n–1) are given velocity v to the right whereas blocks 2, 4, 6,......2n are given velocity v to the left. All collisions between blocks are perfectly elastic. Calculate the total number of collisions that will take place.

Figure shows four blocks that are being pulled along a smooth horizontal surface.The masses of the blocks and tension in one cord are given.The pulling force F is
