This discussion board is a place to discuss our Daily Challenges and the math and science
related to those challenges. Explanations are more than just a solution — they should
explain the steps and thinking strategies that you used to obtain the solution. Comments
should further the discussion of math and science.

When posting on Brilliant:

Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .

Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.

Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.

Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

1 case)The drop would be perfectly spherical because sphere is the only shape with maximum volume but minimum surface area , so due to surface tension , it would be spherical.

2 case)I think its because when a perfectly spherical drop falls , it expiriences 'comparitively' low pressure at the front than at the end , so the end of the drop is squeezed while the front part is able to retain more spherical surface.

Okay, so o e more factor is that the tail of the rain drop is the water that was left behibd while falling but is still attached to rain drop. So, is my answer correct , sir?

@Utkarsh Dwivedi

I have already written the correct answer.. refer to my earlier comments with a diagram.
The diagram shows you how the shape of the rain drop should be in case it attains the terminal velocity..!!

And in case when we neglect the air resistance then it should be spherical..!!

I am extremely sorry for making you post same answer twice.......Can you please explain what is ${ P }_{ A },{ P }_{ B }\quad and\quad { P }_{ C }$ and also the relation used in the solution.

Edit: the answer to part 2 may not be a teardrop shape. Check wikipedia.

In second case drop will have more radius of curvature at the bottom or at the top??

more at the bottom, i think

@Kalash Verma What is your answer for the shape of the drop in the two cases??

The answer in second case should be reverse... The top surface should be of more radius of curvature than the bottom one..

I am posting the solution again...!!

Now think why drop is spherical in (i) case??

The radius of curvature will be more at the bottom, but it will not be a teardrop.
