To find the height of the water column raised in a capillary tube, we can use the formula derived from the principles of capillarity. The height \( h \) of the liquid column in a capillary tube is given by: \[ h = \frac{2 \sigma \cos \theta}{\rho g r} \] Where: - \( \sigma \) = surface tension of the liquid (water in this case) ...
