A) \[\frac{q}{4\pi {{\varepsilon }_{0}}(r+R)}\]
B) \[\frac{q}{4\pi {{\varepsilon }_{0}}R}\]
C) \[\frac{q}{4\pi {{\varepsilon }_{0}}(r+R)}\]
D) Zero
Correct Answer: B
Solution :
After connection, the total charge on inner conductor transfers to outer one and in this situation potential of sphere B is given as \[{{V}_{B}}=\frac{q}{4\pi {{\varepsilon }_{0}}R}\] Because both the spheres will attain an equal potential.You need to login to perform this action.
