Two similar springs \( P \) and \( Q \) have spring constants \( K_{P} \) and \( K_{Q} \), such that \( K_{P}K_{Q} \). They are stretched, first by the same amount (case a), then by the same force (case b). The work done by the springs \( W_{P} \) and \( W_{Q} \) are related as, in case (a) and case (b), respectively [AIPMT (Cancelled) 2015]
(a) \( W_{P}=W_{Q} ; W_{P}=W_{Q} \)
(b) \( W_{P}W_{Q} ; W_{Q}W_{P} \)
(c) \( W_{P}W_{Q} ; W_{Q}W_{P} \)
(d) \( W_{P}=W_{Q} ; W_{P}W_{Q} \)
