Which of the following cannot be explained on the basis of Bernoulli's principle?

Options

  1. ALift on an aircraft's wing
  2. BInk filler
  3. CSwing of a cricket ball
  4. DAtomizer

Correct answer

B. Ink filler

Step-by-step solution

Ink filler works on the principle of both surface tension and pump. Vacuum in the pen pulls the ink in the bottle to the pen. This ink travels in the pen tip through small openings due to surface tension.
