Water rises up to a height of 4 ~cm in a capillary tube. The lower end of the capillary tube is at a depth of 8 ~cm below the water level. The mouth pressure required to blow an air bubble at the lower end of the capillary will be ' X ' cm of water, where X is equal to

Options

  1. A10
  2. B8
  3. C6
  4. D12

Correct answer

D. 12

Step-by-step solution

At the lower ends of the tube, the total pressure is due to height of water column in the container plus the height of water in the capillary. Total pressure is due to 8+4=12 ~cm of water.
