A hollow stirrer that has a diameter of \(1.0 \mathrm{~mm}\) is inserted into a cup of water at \(20^{\circ} \mathrm{C}\). The surface tension of water at that temperature is \(\gamma=7.28 \times 10^{-2} \mathrm{~N} / \mathrm{m}\). What is the mass of the water supported by the surface tension in the stirrer?
