JEE Main 2020 Physics question

A capillary tube made of glass of radius 0.15 mm is dipped vertically in a beaker filled with methylene iodide (surface tension = 0.05 , density = 667 ) which rises to height h in the tube. It is observed that the two tangents drawn from liquid-glass interfaces (from opp. sides of the capillary) make an angle of 60° with one another. Then h is close to (g = 10 ).

• (A)0.137 m
• (B)0.172 m
• (C)0.087 mCorrect
• (D)0.049 m
