The only doubt you have is of the direction, ryt? The question says that it moves from P to Q and loses an amount of potential energy. This means that it accelerates in the direction of displacement.
if this isn't clear, suppose the diagram's right to be ground. when an object falls down towards the ground, ( towards right in diagram) it accelerates downwards (in --> direction) and loses G.P.E. this is just an example of a similar situation for better understanding.
Hope it helps. :)

ok heres how i did it, keep in mind that F will be the same even if l changes. Now if l decreases, its area decreases your now putting the same force on a smaller area so its extension will increase. and if l increases, its area increases your putting the same F on a larger area now so the extension will be lesser,and so they are inversely proportional.
