Right Answer is: A

SOLUTION

Explanation:

Surface Tension: It is defined as force per unit length in the plane of the liquid surface at right angles to either side of an imaginary line drawn to the surface.

Mathematically, 

\(Surface\;Tension = \frac{{Force}}{{Length}}\)

  • It is the tendency of the liquid surface to shrink into a minimum surface area.
  • The SI Unit of surface tension is N m-1
  • It allows insects to float and slide on the water surface, usually more dense than water
  • The molecules at the surface have unbalanced force rather than molecules at deeper and the resultant force moves downward this is surface tension.
  • Dimensional formula is MT-2
