The question as text
A student investigates the behaviour of a liquid inside a narrow tube, as shown in Fig. 2.1. liquid h d Fig. 2.1 (not to scale) When the tube is placed in the liquid, the liquid rises in the tube. The student measures the internal diameter d of the tube and the maximum height h that the liquid rises in the tube. The experiment is repeated for tubes of different diameter. It is suggested that h and d are related by the equation h = 4σ dρg where ρ is the density of the liquid, g is the acceleration of free fall and σ is a constant. 1
