तीन द्रवों के घनत्व क्रमश: P1, P2 तथा P3(P1 > P2 > P3) हैं। तीनों द्रवों का पृष्ठ तनाव T समान है। तीन सर्वसम केशिकाओं में तीनों द्रव समान ऊँचाई तक चढ़ते हैं। यदि इन द्रवों के लिए स्पर्श कोण क्रमश: \(\theta_1\)\(\theta _2\) तथा \(\theta_3\) है, तो निम्नलिखित में से कौनसा सम्बन्ध ठीक होगा:

(a) \(\pi > \theta _1> \theta_2 > \theta_3 < \frac{\pi}{2}\)

(b) \(\frac{\pi}{2}> \theta_1>\theta_2>\theta_3\ge 0\)

(c) \(0 < \theta_1 < \theta_2< \theta_3 < \frac{\pi}{2}\)

(d)\(\frac{\pi}{2}< \theta_1<\theta_2>\theta_3<\pi\)
