The surface tension of soap solution is 0.3 `(N)/(m)`. The work done in blowing a soap bubble of surface area `40cm^(2)`, (in J) is

A

`1.2xx10^(-4)`

B

`2.4xx10^(-4)`

C

`12xx10^(-4)`

D

`24xx10^(-4)`

Text Solution

Verified by Experts

The correct Answer is:
B
In case of soap bubble
`W=Txx2xxDeltaA=0.03xx2xx40xx10^(-4)=2.4xx10^(-4)J`
