Question

Small droplets of a liquid are generally more spherical in shape than large drops of the same liquid because :

• A. force of surface tension is equal and opposite to the force of gravity.
• B. force of surface tension predominates the force of gravity.
• C. force of gravity predominates the surface tension.
• D. force of surface tension and force of gravity act in the same direction and are equal.

Answer 1

The correct option is B force of surface tension predominates the force of gravity.

In small drop, surface tension can withstand small gravitational force but in case of large drops, gravitation force dominates the surface tension causing the big drop to bulge more.
