22 lis 2019 · Science > Physics > Surface Tension > Numerical Problems on Surface Tension. Example – 1: A needle 5 cm long can just rest on the surface of the water without wetting. What is its weight? Surface tension of water = 0.07 N/m. Given: Length of needle = l = 5 cm = 5 × 10-2 m, Surface tension = T = 0.07 N/m. To Find: Weight of needle = F ...
Cohesive forces between molecules cause the surface of a liquid to contract to the smallest possible surface area. This general effect is called surface tension. Molecules on the surface are pulled inward by cohesive forces, reducing the surface area.
