Two similar springs P and Q have spring constants Kp and KQ, such that KP > KQ.They are stretched first by the same amount (case a), then by the same force (case b). The work done by the springs WP and WQ are related as in case (a) and case (b) respectively

Ans Wp > WQ ; WQ > WP

Neet 2015 | W P E Q 3 |It’s a kind of unseen qus at that time . Work done by spring was beautifully used . In the case ( a ) work done can easily be compared but in case ( b ) you need to find first relation between elongations in terms of spring constant and then you can compare work done by spring force.
