त्रिज्या \( R \) की एक बड़ी बूँद को समान त्रिज्या \( r \) की \( n \) बूँदों में स्प्रे करने में किया गया कार्य है ( \( T \) पषष्ठ-तनाव, \( P \) वायूमण्डलीय दाब है) :
(A) \( R n^{2 / 3} T \)
(B) \( 4 \pi R^{2} T\left(n^{1 / 3}-1\right) \)
(C) \( \left(n^{2 / 3}-1\right) T R^{2} \)
(D) \( \pi R^{2} T\left(n^{1 / 3}-1\right) \)
