Two soap bubbles have radii in the ratio of $4:3$. What is the ratio of work done to blow these bubbles?
W is the work done, when a bubble of volume V is formed from a solution. How much work is required to be done to form a bubble of volume 2V?
The surface energy of a liquid drop of radius r is proportional to:
A mercury drop of radius 1 cm is broken into 106 droplets of equal size. The work done is
