The amount of work done in blowing a soap bubble such that its diameter increases from d to D is (T= surface tension of the solution)
Text Solution
Verified by ExpertsThe correct answer is:
D
$W = T \times 8\pi (r_2^2 - r_1^2) = T \times 8\pi \left(\frac{D^2}{4} - \frac{d^2}{4}\right)$
$= 2 \pi (D^{2} - d^{2}) T$
