Two spherical soap bubbles of radii r(1)...

Two spherical soap bubbles of radii `r_(1)` and `r_(2)` in vacuum coalesce under isothermal condition . The resulting bubble has a radius R such that .

A

`R=frac((r_(1)+r_(2)))(2)`

B

`R=[frac(r_1r_2)((r_(1)+r_(2)))`

C

`R=sqrt((sqrt_1^2+r_2^2))`

D

`R=r_1+r_2`
