Question

Findthe difference of air pressure between the inside and outside of a soap bubble 5mm in diameter in the surface tension is 1.6 N/ m

Answer 1

Here is ur answer...

Answer 2

Answer:

Given: diameter(d)= 5mm

Therefore radius (r) = 2.5 mm or 0.25*10^-2m tension T = 1.6 N/m

Pi - Po = 4T/r

= 4 * 1.6/0.25*10^-2

= 4 * 160/ 1/4

= 2560N/meter sqr
