but the surface area exposed will also be less so air resistance will take more time to bring the drop to its terminal velocity.. nahi?

Well, I thought that way first, but maybe the surface area wala factor is not as effective as is the weight? :D

Projectile motion is like 2 different motions happening in a body, one is vertical and the other is horizontal.
It's like throwing a ball up vertically at a height h and throwing a ball horizontally with constant speed both happens at the same time
