Which of the following statement is not true about angle of contact?

Water rises to a height of $16.3cm$ in a capillary of height $18cm$ above the water level.If the tube is cut at a height of $12cm$:

Two vertical glass plates 1 mm apart are dipped into water, How high will the water rise between the plates, if the surface tension of water is 70 dyne/cm?

A drop of some liquid of volume $0.04{cm}^3$ is placed on the surface of a glass slide. Then another glass slide is placed on it in such a way that the liquid forms a thin layer of area 20${cm}^2$ between the surface of the two slides. To seperate the slides a force of $16\times 10^3$ dyne has to be applied normal to the surface. The surface tension of the liquid is (in dyne ${cm}^{-1}$)

The ratio of tensions in the string connected to the block of mass $m_2$ in Fig. A.11 $(a)-(b)$, respectively, is (friction is absent everywhere): $[m_1=50kg,m_2=80kg$ and $F=1000N]$

Two mercury drops (each of radius r) merge to form bigger drop. the surface energy of the bigger drop, if T is the surface tension , is

Drops of liquid of density p are floating in a liquid of density ${\rho }_L$. If the surface tension is T, the radius of the drop will be 

Inside a soap bubble of diameter $0.35$ cm, the air pressure is equal to the 8 mm of water outside it, the surface tension of solution will be
( $\rho =1\mathrm{g}\mathrm{m}/\mathrm{c}\mathrm{c})$

In order to raise a block of mass $100$ kg a man of mass $60$ kg fastens a rope to it and passes the rope over a smooth pulley. He climbs the rope with an acceleration $\frac{5g}{4}$ relative to rope. The tension in the rope is $(g=10m{s}^{-2})$.

A sphere is just immersed in a liquid. Find the ratio of hydrostatic force acting on top and bottom half of the sphere.
