Water rises upto a 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]

Options:

Answer:

Solution:

(D) $h = \frac{2 T c o s θ}{r ρ g} ∴ h \propto \frac{1}{g}$ For a lift going down with acceleration $a$ , the effective value of $g$ is $g^{'} = g - a$ $g^{'} = g - a$ $g^{'} < g ∴ h$ will increase.
