Detailed Solution
Download Solution PDFप्रयुक्त अवधारणा:
• छोटी बूंदों के आयतन का योग = बड़ी बूंद का आयतन
• गोले का आयतन = 4/3 × π × r3
गणना:
छोटी बूंदों की कुल संख्या 0.1% of 1.728 × 106 = 1728
मान लेते है कि बड़े बुलबुले का दायरा R मिमी है
⇒ 1728 × 4/3 × π × (2/2)3 = 4/3 × π × R3
⇒ R3 = 1728
⇒ R = 12 मिमी or 1.2 सेमी
व्यास 2 × 1.2 = 2.4 सेमी
∴ सही उत्तर है 2.4 सेमी
