Q 1928656501.     Two narrow bores of diameters 3 mm and 6
mm are joined together to form U shaped tube
open at both ends. If the U tube contains water
what is the difference in its levels in the two
limbs of the tube? Surface tension of water at
the temperature of the experiment
`= 7.3 xx 10^(-2) Nm^(-1)` Take the angle of contact
to be zero, and density of water `= 1 0^3 kgm^(-3)`
(`g = 9.8 ms^(-2)`).
