A capillary tube stands with its lower end dipped into liquid for which the angle of contact is 90^ . The liquid will

Options

  1. Aneither rise nor fall.
  2. Bget depressed only.
  3. Crise only.
  4. Drise upto the top of the tube.

Correct answer

A. neither rise nor fall.

Step-by-step solution

aligned & h = 2 ~T g r & ~h = 2 ~T 90 g r & ~h =0^ ( 90^ =0 ) aligned Hence, the liquid will neither rise nor fall.
