Homework Statement
A capillary is dipped in water vessel kept on a freely falling lift, then
a)water will not rise in the tube
b)water will rise to the maximum possible height of the tube
Homework Equations
W=2[tex]\pi[/tex]r S cos[tex]\theta[/tex]
or h=(2S cos [tex]\theta[/tex])/(r[tex]\rho[/tex]g)
The Attempt at a Solution
as this is the case of free fall g tends to 0 hence h tends to infinity hence the option (b)
but it might also mean that cos [tex]\theta[/tex]=0, i.e, the water doesn't rise at all, hence the option (a)
which logic is correct?
