Radius of a soap bubble is increased from R to 2 R work done in this process in terms of surface tension is

A

`24piR^(2)S`

B

`48piR^(2)S`

C

`12piR^(2)S`

D

`36piR^(2)S`

Text Solution

Verified by Experts

The correct Answer is:
A
`W = 8piT (R_(2)^(2)-R_(1)^(2)) = 8piS[(2R)^(2)-(R )^(2)] = 24 pi R^(2)S`
