Question
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
-
WP =WQ ;WP> WQ
-
WP =WQ ;WP= WQ
-
WP > WQ ;WQ> WP
-
WP <WQ ; WP< WQ
Solution
C.
WP > WQ ;WQ> WP
Given KP>KQ
In case (a) the elongation is same
