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

Text Solution

Verified by Experts

Because of the surface tension, a liquid drop tends to acquire minimum surface area. Sphere is the only shape having minimum surface area. Therefore, liquid drop is spherical in shape.
