If the radius of a soap bubble is four times that of another, then the ratio of their pressures will be

A

`1:4`

B

`4:1`

C

`16:1`

D

`1:16`

Verified by Experts

The correct Answer is:

A

Excess pressure inside a soap bubble `DeltaP = (4T)/(r ) implies (DeltaP_(1))/(DeltaP_(2)) = (r_(2))/(r_(1)) = 1:4`
