Surface tension of a soap bubble is 2.0×10−2 N m−1 . Work done to increase the radius of soap bubble from 3.5 cm to 7 cm will be : [Take π=227 ]
Question
Solution 1
The work done to increase the radius of a soap bubble can be calculated using the formula for the work done on a bubble, which is:
W = 8πr₁r₂σ
where:
- W is the work done,
- r₁ and r₂ are the initial and final radii of the bubble,
- σ is the surface tension.
Given:
- σ = 2.0×10−2 N m−1,
- r₁ = 3. Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
