Small droplets of a liquid are usually more spherical in shape than larger drops of the same liquid because
Force of surface tension is equal and opposite to the force of gravity
Force of surface tension predominates the force of gravity
Force of gravity predominates the force of surface tension
Force of gravity and force of surface tension act in the same direction and are equal
Force due to surface tension dominates the force due to gravity for smaller droplets .Hence they are usally more spherical in shape than larger drops.
