The radii of two soap bubbles are $$r_1$$ and $$r_2$$. In isothermal condition they combine with each other to form a single bubble. The radius of resultant bubble is

A
$$\mathrm{R}=\frac{\mathrm{r}_1+\mathrm{r}_2}{2}$$
B
$$\mathrm{R}=\mathrm{r}_1\left(\mathrm{r}_1 \mathrm{r}_2+\mathrm{r}_2\right)$$
C
$$\mathrm{R}=\sqrt{\mathrm{r}_1^2+\mathrm{r}_2^2}$$
D
$$\mathrm{R}=\mathrm{r}_1+\mathrm{r}_2$$

The work done in blowing a soap bubble of radius $$\mathrm{R}$$ is '$$\mathrm{W}_1$$' at room temperature. Now the soap solution is heated. From the heated solution another soap bubble of radius $$2 \mathrm{R}$$ is blown and the work done is '$$\mathrm{W}_2$$'. Then

A
$$\mathrm{W}_2=\mathrm{W}_1$$
B
$$\mathrm{W}_2=4 \mathrm{~W}_1$$
C
$$\mathrm{W}_2<4 \mathrm{~W}_1$$
D
$$\mathrm{W}_2=0$$
