Two spheres A & B of radii \(4 \mathrm{~cm} \& 6 \mathrm{~cm}\) are given charges of \(80 \mu \mathrm{C} \& 40 \mu \mathrm{C}\) respectively. If they are connected by a fine wire, the amount of charge flowing from one to the other is
- A \(32 \mu \mathrm{C}\) from B to A
- B \(32 \mu \mathrm{C}\) from A to B
- C \(20 \mu \mathrm{C}\) from A to B
- D \(16 \mu \mathrm{C}\) from B to A
Answer & Solution
Correct Answer
(B) \(32 \mu \mathrm{C}\) from A to B
Step-by-step Solution
Detailed explanation
\(\mathrm{Q}_1=80 \mu \mathrm{C}, \mathrm{Q}_2=40 \mu \mathrm{C}\) \(\mathrm{r}_1=4 \mathrm{~cm}, \mathrm{r}_2=6 \mathrm{~cm}\) \(\therefore \quad\) After connecting wire,…
