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 releated as, in case (a) and case (b), respectively
Options
(a) Wp=Wq;Wp=Wq
(b) Wp>Wq;Wq>Wp
(c) Wp<Wq;Wq<Wp
