A) \[\frac{Q}{2\pi {{\varepsilon }_{0}}R}\]
B) \[\frac{3Q}{2\pi {{\varepsilon }_{0}}R}\]
C) \[\frac{3Q}{4\pi {{\varepsilon }_{0}}{{R}^{2}}}\]
D) \[\frac{4Q}{4\pi {{\varepsilon }_{0}}{{R}^{2}}}\]
Correct Answer: C
Solution :
Electric field at a distance R is only due to sphere because electric field due to shell inside it is always zero. Hence electric field =\[\frac{1}{4\pi {{\varepsilon }_{0}}}.\frac{3Q}{{{R}^{2}}}\]You need to login to perform this action.
