Question 11. Two soap bubbles have radii in the ratio of 4 : 3. What is the ratio of work done to below these bubbles? (a) 4 : 3 (b) 16 : 9 (c) 09 : 16 (d) 3 : 4
Correct option is B) Work done to brust a soap bubble is change in surface energy which is equal surface Tension × Area. Workdone α Area α r 2 Solution. The ratio of work done to blow the bubbles is 16 : 9.
