Surface tension acts

Is surface tension is vector ?

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

At critical temperature, the surface tension of a liquid is......

Statement I: Surface tension has the same units as force gradient. Statement II: Surface tension is the force gradient along the surface of liquid.

Calculate the radius of capillary tube if water rise to a height 4.5 cm . Surface tension of water is 72 dyne /cm .

When one end of the capillary is dipped in water, the height of water column is 'h' . The upward force of 105 dyne due to surface tension is balanced by the force due to the weight of water column . The inner circumference of the capillary is (Surface tension of water = 7 xx 10^(-2) N//m )

S.I. Unit of surface tension is:

S.I. Unit of surface tension is:

A circular loop of a thin wire of radius (7//pi) cm is suspended from one arm of a balance. The plane of the loop is in contact with the surface of soap solution. If the pull on the loop due to surface tension is found to be (0.6xx10^-3) kg wt, then the surface tension of soap solution will be, (Angle of contact theta=0 )
