Assertion
Small liquid drops assume a spherical shape.
Reason
Due to surface tension liquid drops tend to have the minimum surface area.
$\left( a \right)$ Both assertion and reason are correct and the reason is the correct explanation for the assertion.
$\left( b \right)$ Both assertion and reason are correct but the reason is not the correct explanation for the assertion.
$\left( c \right)$ The assertion is correct but the reason is incorrect.
$\left( d \right)$ Both assertion and reason are incorrect.

Hint So to answer and verify the statement we should have the concept of the surface tension. Surface tension is the propensity of the liquid surfaces to contract into the base surface zone conceivable. It can be dictated by the distinction of the collaborations between the atoms of the liquid with the particles of the container or the atoms of the capacity divider.

Complete Step By Step Solution The free surface of a fluid drop cries to get the least surface territory because of surface tension. For a given volume. The surface area of the circle is least, the fluid drops gain circle is least, and the fluid drops get spherical shape.
Therefore, we can say that both points verify each other. And the reason is the correct
explanation of the given statement.

Hence, the option $\left( a \right)$ will be correct.

Additional information Surface tension emerges from the firm powers applied between atoms of the droplets. This causes the water to drop to receive a close to the circular shape. The same thing applies to cleanser bubbles, yet for their situation, the surface tension powers are higher and they structure a round shape.
A surface strain is liable for the state of fluid droplets. Albeit handily distorted, droplets of water will in general be maneuvered into a circular shape by the durable powers of the surface layer. Without different powers, including gravity, drops of for all intents and purposes all fluids would be roughly circular. The round shape limits the essential "wall tension" of the surface layer as per Laplace's law.

Note On account of spinning items, for example, planets, stars, worlds, or even a turning drop of water, all particles that are at a range of its pivot of turn will encounter centripetal speeding up, which will make the sides pull away from the center.
