A) Zero
B) \[\frac{q}{4\pi {{\varepsilon }_{0}}}\left[ \frac{1}{r}-\frac{1}{{{R}_{1}}}+\frac{1}{{{R}_{2}}} \right]\]
C) \[\frac{q}{4\pi {{\varepsilon }_{0}}}\left[ \frac{1}{r}-\frac{1}{{{R}_{1}}} \right]\]
D) None of these
Correct Answer: B
Solution :
[b] \[V={{V}_{q}}+{{V}_{-qin}}+{{V}_{qin}}=\frac{q}{4\pi {{\in }_{0}}}\left[ \frac{1}{r}-\frac{1}{{{R}_{1}}}+\frac{1}{{{R}_{2}}} \right]\]You need to login to perform this action.
