A soap bubble has radius

'r'

. What will be the value of work done if its radius increases to three times of initial value without changing temperature (surface tension of soap solution is

'T'

)

View answer and explanation

Correct option: A

64\,\pi {r^2}T

Option A (

64\,\pi {r^2}T

) is correct because it represents the work done in increasing the surface area of the soap bubble, considering both inner and outer surfaces.
