Small liquid drops assume spherical shape because:

چھوٹے مائع قطرے کروی شکل اختیار کر لیتے ہیں کیونکہ

Of adhesion

Of the pressure from all sides

Of the gravitational force

The liquid tends to have minimum surface area dure to surface tension

Explanation

Spherical shape is because drop always tends to acquire minimum surface area due to the surface tension, and for a given volume, the surface area of sphere is minimum.
