Question

R the rain drops always sperical? account for your answer.?

Answer 1

Surface tension always tries to pull a raindrop into a spherical shape.  However, aerodynamic forces on the droplet as it falls through the air flatten the bottom and cause ripples to run along the sides.  Thus raindrops are not precisely spherical.

A droplet in a weightless environment will form a perfect sphere, however.

Answer 2

Dip a finger into a bowl of water and then take it out.Now watch the drop of water as it trickles down the finger and drops down.You will notice that the drop of water acquires a spherical shape.Place a drop of mercury on a smooth surface.It attains a sherical shape;this phenomena is due to the cohesive force(force of attraction between the molecules of same element) which brings the molecules together.

But then,why does it take a sphericl shape,why not a cubic one?.This is because, out of all mutidimensional geometric figures,sphere has the least surface area.Thus all particles try their best to attain a spherical shape in order to reduce their surface area.It is for the same reason that when you pour any liquid in space they attain a spherical shape.But this is not the case with solids since their molecules are compactly packed and can not be displaced.

So,in the same way rain drops also attain sherical shape.But,due to frictional forces or aerodynamic forces,their bottoms are slightly flattened while falling.
