A sphere '1' with radius \(\mathrm{R}\) has charge \(\mathrm{q}\). Sphere '2' with radius \(3 \mathrm{R}\) is far from sphere ' 1 ' and is initially uncharged. If the two spheres are now connected with a thin conducting wire, then the ratio \(\frac{\sigma_1}{\sigma_2}\) of the surface charge densities is
- A 2
- B 2.5
- C 3
- D 9
Answer & Solution
Correct Answer
(C) 3
Step-by-step Solution
Detailed explanation
\( \mathrm{q}_{\mathrm{i}}=\mathrm{q}_{\mathrm{f}} \Rightarrow \mathrm{q}=\mathrm{q}_1+\mathrm{q}_2 \) As the sphere are connected by wire…
