Statement-A: If the angle of contact is equal to

\pi / 2

then the level of liquid in capillary is same as outside the capillary.
Statement-B: If the angle of contact is less than

\pi / 2

then the liquid rises in the capillary.

View answer and explanation

Correct option: A

Statement A is true and statement B is true

Option A (Statement A is true and statement B is true) is correct because an angle of contact of

\pi/2

implies no capillary action, and an angle less than

\pi/2

results in capillary rise.

The tube is depressed more so that the top of capillary tube is only one cm above the liquid. Then the apparent angle of contact between the solid and liquid is An object weights
