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...
