The unit of the surface tension is -

Correct option is B

· Surface Tension:
· Surface tension is the force acting along the surface of a liquid, per unit length, which causes the liquid to behave as if its surface were covered with a stretched elastic sheet.
· It is measured in dynes per centimeter (dynes/cm) in the CGS system.
· Detailed Explanation:
· 1 dyne = 10⁻⁵ newtons.
· Surface tension is force per unit length, not per unit area (as in pressure).
