Which of the following cannot be explained on the basis of Bernoulli's principle?
- A Lift on an aircraft's wing
- B Ink filler
- C Swing of a cricket ball
- D Atomizer
Answer & Solution
Correct Answer
(B) Ink filler
Step-by-step Solution
Detailed explanation
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.
