Which one of the following is defined as force per unit length?a)surfa...
Force per unit length, also known as tension, is defined as the force exerted by a stretched string, wire, or any other elongated object per unit length. It is represented by the symbol "T" and is measured in units of force per unit length, such as newtons per meter (N/m) or dynes per centimeter (dyn/cm).

Surface tension, compressibility, capillarity, and viscosity are all different properties of fluids, but they are not directly related to force per unit length.

Explanation of the options:

a) Surface tension: Surface tension is the property of a liquid that causes its surface to behave like an elastic sheet. It is defined as the force acting parallel to the surface of a liquid per unit length. However, surface tension is not the same as force per unit length, as it acts parallel to the surface and not along the length of an elongated object.

b) Compressibility: Compressibility is a measure of how much a substance can be compressed under the action of an external force. It is defined as the change in volume per unit change in pressure. Compressibility is not directly related to force per unit length.

c) Capillarity: Capillarity is the phenomenon of the rise or fall of a liquid in a narrow tube, such as a capillary tube. It is caused by the combination of adhesive and cohesive forces. Capillarity is not directly related to force per unit length.

d) Viscosity: Viscosity is the measure of a fluid's resistance to flow. It is defined as the internal friction between different layers of a fluid as they slide past each other. Viscosity is not directly related to force per unit length.

Conclusion:
The correct answer is option 'A' - surface tension. Surface tension is defined as force per unit length and represents the force acting parallel to the surface of a liquid per unit length. It is a property that arises due to the cohesive forces between liquid molecules at the surface.
