An open cappillary tube contains a drop of water. The internal diameter of the capillary tube is `1mm`. Daternube tge radii if curvature of the upper and lower meniscuses in each case. Consider the wetting to be complete. Surface tension of water `= 0.073 N//m`. `(g = 9.8 m//s^(2))`
When the tube is in its vertical position, the drop forms a column with a length of `2 cm`.
A. `0.5 mm, 1.52 mm`
B. `0.5 mm, 1.46 mm`
C. `0.5 mm`, lower surface will be flat
D. `0.4 mm, 1.46 mm`
