Droplets of a liquid are usually more spherical in shape than larger drops of the same liquid because the force of

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 force of surface tension

D

force of gravity and force of surface tension act in the same direction and are equal

Text Solution

Verified by Experts

The correct Answer is:
B
For small drops, force of surface tension predominates gravitational force and so, they are more spherical.
