An air bubble of radius is at a depth of below the free surface of a liquid column. If the surface tension and density of the liquid is and respectively, by what amount is the pressure inside the bubble greater than the atmospheric pressure?
(Take )
- A
- B
- C
- D
Answer & Solution
Correct Answer
(B)
Step-by-step Solution
Detailed explanation
Excess pressure will be due to two factors, first will be due to depth and the second will be due to the surface tension. Also number of free surface of an air bubble inside the liquid will be only one. Therefore, excess pressure inside the air bubble in the liquid will be,…
