Mechanical Properties of Fluids

142996 A glass capillary tube of inner diameter 0.28 $\mathrm{mm}$ is lowered vertically into water in a vessel. The pressure to be applied on the water in the capillary tube so that water level in the tube is same as that in the vessel (in $\mathrm{Nm}^{-2}$ ) is (Surface tension of water $=0.07 \mathrm{Nm}^{-1}$ )
Atmospheric pressure $=10^{5} \mathrm{Nm}^{-2}$

143000 Water rises upto height ' $h$ ' in a capillary tube on the surface of the earth. The value of ' $h$ ' will increase if the experimental setup is kept in $g=$ acceleration due to gravity

1 a lift going upward with a certain acceleration
2 accelerating train
3 a satellite rotating close to earth
