How much high does the water rise? If the tube is now lowered unitil 30 mm of its length is above the surface of water, what happens? Surface tension of water is 75 dyne/cm and g = 1000 cm/s^2

Consider a rain drop falling at terminal speed. For what radius (R) of the drop can we disregard the influence of gravity on its shape? Surface tension and density of water are T and ρ respectively.
