A) \[\frac{(q+Q)}{4\pi {{\varepsilon }_{0}}}\frac{2}{R}\]
B) \[\frac{2Q}{4\pi {{\varepsilon }_{0}}R}\]
C) \[\frac{2Q}{4\pi {{\varepsilon }_{0}}R}-\frac{2q}{4\pi {{\varepsilon }_{0}}R}\]
D) \[\frac{2Q}{4\pi {{\varepsilon }_{0}}R}+\frac{q}{4\pi {{\varepsilon }_{0}}R}\]
Correct Answer: D
Solution :
Electric potential at P \[V=\frac{k.Q}{R/2}+\frac{k.q}{R}\] \[=\frac{2Q}{4\pi {{\varepsilon }_{0}}R}+\frac{q}{4\pi {{\varepsilon }_{0}}R}\]You need to login to perform this action.
