Two soap bubbles coalesce.It noticed that, whilst joined together, the radii of the two bubbles are a and b where a>b.Then the radius of curvature of interface between the two bubbles will be

A

r

B

`0`

C

infinity

D

`(r )/(2)`

Text Solution

Verified by Experts

The correct Answer is:
C
Radius of curvature, `r=(r_(1)r_(2))/(r_(2)-r_(1))=oo`, i.e., a straight plane.
