Your questions is incomplete the complete question should be.

Ina capillary tube experiment a vertical 30 cm long capillary tube is dipped intothe water . It rises to a height of 10cm due to capillary action.If this experiment is conducted in a free falling elevator the length of the water column becomes?

•GIVEN:

→Length of capillary=30cm

→Water rises to a height (h)=10cm

$\red{\boxed{\green{Answer}}}$

We know that:

h= $\frac{2T}{\rho*g*r}$

In this case we will take g as ${g}_{eff}$ so the free falling elevator will have g as 0.

So we get the value of h as ∞

Thus the lenght of water column will be as same as the length of capillary tube that is 30cm
