Pressure inside a soap bubble is greater than the pressure outside by an amount : (given : R = Radius of bubble S = Surface tension of bubble)

Options

  1. A2 S R
  2. B4 R S
  3. CS R
  4. D4 ~S R

Correct answer

D. 4 ~S R

Step-by-step solution

There are two liquid-air surfaces in bubble so P =2 ( 2 ~S R )= 4 ~S R
