Momentum and CollisionHard
Question
Two soap bubbles each of radius r are touching each other. The radius of curvature of the common surface will be :
Options
A.infinite
B.2r
C.r
D.r / 2
Solution
rcommon = 
[r2 > r1]here r1 = r2, so rcommon = ∞
[r2 > r1]here r1 = r2, so rcommon = ∞Create a free account to view solution
