Two rain drops falling through air have radii in the ratio \(1: 2\). They will have terminal velocity in the ratio
- A \(1: 2\)
- B \(4: 1\)
- C \(1: 4\)
- D \(2: 1\)
Answer & Solution
Correct Answer
(C) \(1: 4\)
Step-by-step Solution
Detailed explanation
\(\mathrm{V} \propto \mathrm{r}^{2}\)
\(\frac{\mathrm{V}_{1}}{\mathrm{~V}}=\left(\frac{1}{2}\right)^{2}=\frac{1}{4}\)
\(\frac{\mathrm{V}_{1}}{\mathrm{~V}}=\left(\frac{1}{2}\right)^{2}=\frac{1}{4}\)
