The figure shows three arrangements of a block attached to identical springs that are in their relaxed state when the block is centered as shown. Rank the arrangements according to the magnitude of the net force on the block, largest first, when the block is displaced by distance d (a) to the right and (b) to the left. Rank the arrangements according to the work done on the block by the spring forces, greatest first, when the block is displaced by d (c) to the right and (d) to the left.

Answer #1

The restoring force acting on a block attached to a spring is given as, F=-kr Here, F is the force, k is the spring constant,In case (3), when the block is displaced to the right, the magnitude of the restoring force acting on the block is, F = kd +Work done in case (2) is, ws=ke + ka + kad Work done in case (3) is, 2 = 2kd Hence, the ranking of the arrangements according
