Question
Explain why
A drop of liquid under no external forces is always spherical in shape.
✓

Answer

A liquid tends to acquire the minimum surface area because of the presence of surface tension. The surface area of a sphere is the minimum for a given volume. Hence, under no external forces, liquid drops always take spherical shape.
