The amount of work done in blowing a soap bubble such that its diameter increases from d to

D

is (

S =

surface tension of solution)

View answer and explanation

Correct option: B

2\pi \left( {{D^2} - {d^2}} \right)S

Option B is correct because the work done is the product of surface tension and the change in surface area of the soap bubble, considering both surfaces.
