Answer 1

Hey, here is your answer for your brilliant question:

If two soap bubbles of equal radii R coalesce then the radius of curvature of interface between two bubbles will be

(a) infinity

Hope this helps!

Answer 2

Hey Dear,

◆ Answer -

(a) infinity

◆ Explanation -

# Given -

R1 = R2 = R

# Solution -

Radius of curvature of interface between two bubles is calculated by -

1/r = 1/R1 - 1/R2

1/r = 1/R - 1/R

1/r = 0

r = ∞

Therefore, If two soap bubbles of equal radii R coalesce then the radius of curvature of interface between two bubbles will be infinity.

Hope this helped you. Thanks for asking..
