Question

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 Nm−1.

Answer 1

The water surface rises to a height of 1.5 cm

Explanation:

• Surface tension of water T = 0.075 nm  
• Separation of glass plate d =  1 mm = 10^-3 m
• Density of water  = 10^3  kg/m ^3
• Now the rise in the level of water can be calculated as:

Height "h" =   2 × 0.075 / 10^−3  × 10^ 3  × 10

Height "h" = 0.015 m = 1.5 cm

Thus the water surface rises to a height of 1.5 cm
