An open capillary tube contains a drop of water. When the tube is in its vertical position, the drop forms a column with a length of a 2cm, b. 4cm, and c. 2.98cm. The internal diameter of the capillary tube is 1 mm. Determine the radii of curvature of the upper and lower meniscuses in each case. Consider the wetting to be complete. Surface tension of water =0.0075 N/m
