The spherical shape of rain-drop is due to
Text Solution
Verified by ExpertsThe correct answer is:
B
Step 1: Understand that the shape of a rain-drop is influenced by various forces acting on it.
Step 2: The primary factor that determines the shape of small fluid drops in the air is the surface tension. Surface tension causes the liquid to minimize its surface area.
Step 3: A spherical shape has the smallest surface area for a given volume, which is why rain-drops take this shape.
Step 4: While gravity and atmospheric pressure act on the droplet, their effect on shape is secondary compared to the dominant role of surface tension.
Therefore, the correct answer is Option B: Surface tension.
