Two air bubbles of radii 0.002 m and 0.004 m of same liquid come together to form a single bubble under isothermal condition. Find the radius of the buble formed. Given surface tension of liquid is `0.072 Nm^(-1)`

Two soap bubbles of radii r_1 and r_2 combine to form a bigger bubble under isothermal conditions. The radius of bigger bubble will be

Two separate air bubbles of raddi 0.002 m and 0.004m formed of same liquid of surface tension 0.7 N//m come together to form a double bubble. The radius of the internal film surface common to both the bubbles is,

Two separate air bubbles (radii 0.002 cm and 0.004 ) formed of the same liquid (surface tension 0.07 N//m ) come together to form a double bubble. Find the radius and the sense of curvature of the internal film surface common to both the bubbles.

Two separate air bubble (radii 0.002 cm and 0.004 ) formed of the same liqid (surface tension 0.07 N//m ) come together to form a double bubble. Find the radius and the sence of curvature of the internal film surface common to both the bubbles.

Two separate air bubbles (radii 0.002 m and 0.004 m) formed of the same liquid (surface tension 0.70 Nm^-1)~ came together to form a double bubble. Find the radius and sense of curvature of the internal film surface common to both the bubbles.

Two soap bubbles of radii 2 cm and 5 cm coalesce under isothermal condition in vaccum, to form a bigger bubble. Find the radius of new bubble.

Two separate air bubbles (radii 0.002 cm and 0.004 cm) formed of the same liquid (surface tension 0.070 N/m) come together to form a double bubble. Radius of curvature of the internal film surface common to both the bubble is concave towards the smaller bubble. Find the radius (in mm) of the internal film surface common to both the bubbles.
