Question

Two soap bubbles of radii 2cm & 4cm join to form a double bubble in air, then radius of curvature of interface is

Answer 1

Explanation:

Given Two soap bubbles of radii 2 cm & 4 cm join to form a double bubble in air, then radius of curvature of interface is

• We know that
• When a smaller bubble come in contact then radius of their interface is given by
•                                                                          = R1 R2 / (R1 – R2)
•                                                                         = 4 x 2 / 4 – 2
•                                                                             = 8/2
•                                                                           = 4 cm
