Assertion- Surface tension has the same units as force gradient.
Reason- Surface tension is the force gradient along the surface of liquid.

A.)Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
B.)Both Assertion and Reason are correct but Reason is not the correct explanation for the Assertion
C.)Assertion is correct but Reason is incorrect
D.)Both Assertion and Reason are incorrect

Explanation

Solution

Hint: Surface tension tends to compress to the smallest region of potential liquid surfaces. Surface tension allows organisms to move and roll along the water surface, typically denser than water. Surface stress at liquid-ice interfaces culminated in a greater attractiveness of liquid molecules (by coherence) than the air molecules (by adhesion).

Step by Step Answer:
Two key structures are at play. First of which is an intrinsic power of fluid bond on the surface molecules. Second, there's a tangential power similar to the liquid top. The net result is the liquid behaves as a woven elastic film covering the back. Since water molecules are comparatively bound to each other by a hydrogen network, water is closer than most other liquids. Water has an enhanced surface tension. Surface friction is a significant influence in the capillary process.

The surface tension of liquid can be determined on the hypothetical direction drawn from a liquid surface as the force per unit length (force gradient), which works perpendicular to the line on each side of the surface and at each point, tangentially to the liquid.
Thus, we can say that the surface tension and the force gradient have the very same dimensions.

Hence, option A is the correct answer.

Note: Tension of the surface has a unit-length intensity or a unit-area strength element. Both are similar, although the word surface energy, which is a more general concept in that it extends even to solids, is popular to be used as it corresponds to energy per unit of space.
