Two vertical parallel glass plates are partially submerged in water. The distance between the plates is \( d \) and the length is \( l \). Assume that the water between the plates does not reach the upper edges of the plates and that the wetting is complete. The water will rise to height ( \( \rho= \) density of water and \( \sigma= \) surface tension of water)
(1) \( \frac{2 \sigma}{\rho g d} \)
(2) \( \frac{\sigma}{2 \rho g d} \)
(3) \( \frac{4 \sigma}{\rho g d} \)
(4) \( \frac{5 \sigma}{\rho g d} \)
