Work `W` is required to form a bubble of volume `V` from a given solution. What amount of work is required to be done to form a bubble of volume `2V` ?

A

W

B

`2^(1//3)W`

C

2 W

D

`4^(1//3)W`

Text Solution

Verified by Experts

The correct Answer is:
D
`W = Txx 2 dA`
` = 40 xx10^(-3) xx2 xx 2xx 10^(-3)=16xx10^(-5)`J
