Two pieces of glass plates placed one upon the other with a little water in between them cannot be separated easily because of:

The spherical shape of a rain-drop is due to

If the surface area of the soap solution is increased,then its surface tension

Why are clothes easily washed by soap or detergent?

What causes the free surface of a liquid to have minimum area?

$A$ wooden stick $2 \, m$ long is floating on the surface of water. The surface tension of water is $0.07 \, N/m$. By putting soap solution on one side of the stick,the surface tension is reduced to $0.06 \, N/m$. The net force on the stick will be ....... $N$.
