A soap bubble of radius \(1.0 \mathrm{~cm}\) is formed inside another soap bubble of radius \(2.0 \mathrm{~cm}\). The radius of an another soap bubble which has the same pressure difference as that between the inside of the smaller and outside of large soap bubble, in metres is
- A \(6.67 \times 10^3\)
- B \(3.34 \times 10^3\)
- C \(2.23 \times 10^3\)
- D \(4.5 \times 10^3\)
Answer & Solution
Correct Answer
(A) \(6.67 \times 10^3\)
Step-by-step Solution
Detailed explanation
Given, radius of first soap bubble \(\left(R_1\right)=2.0 \mathrm{~cm}\) Radius of second soap bubble \(\left(R_2\right)=1.0 \mathrm{~cm}\) We know that, Radius of another bubble having same pressure difference, or, \[ R=\frac{R_1 R_2}{R_1+R_2} \]…
