Two large glass plates are placed vertically and parallel to each other inside a tank of water with separation between the plates equal to 1 mm. Find the rise of water in the space between the plates. Surface tension of water $= 0.075 N / m . ($ Contact angle $= 0^{\circ})$

Options:

Answer:

Solution:

Force balance on the raised column (plates separated by t = 1 mm): $2 T = (h t) ρ g$

$h = \frac{2 T}{ρ g t} = \frac{2 \times 0.075}{1 0 ^{3} \times 10 \times 1 0 ^{- 3}} = 0.015 m = 1.5 cm$ Hence (A).
