The work done in blowing a bubble of radius R is W. What is the work done in making a bubble of radius 2R? Given both the bubble are to be made with the same solution.

A

`W//2`

B

`2W`

C

`4W`

D

`2(1)/(3)W`

Text Solution

Verified by Experts

The correct Answer is:
C
`W=8pi R^(2)T`
`therefore W prop R^(2)`
If radius double, then work done will become four times.
