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)
if water is replaced by another liquid of surface tension \( 2 \sigma \), then the force \( F \) of attraction between two plates would become
(1) \( 2 F \)
(2) \( 4 F \)
(3) \( 8 F \)
(4) \( 16 F \)
