Question
The excess pressure inside the first soap bubble is three times that inside the second bubble then, the ratio of the first to the second bubble will be:
Options
A.1:27
B.3:1
C.1:3
D.1:9
Solution
Excess pressure in first soap bubble,
p1 =
∴ excess pressure inside second bubble,
p2 =
but p1 = 3p2 ⇒
so,ratio of their volumes is,
p1 =
∴ excess pressure inside second bubble,
p2 =
but p1 = 3p2 ⇒
so,ratio of their volumes is,
