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?

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.

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

Teardrop.

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??

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

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..
