A) 6m
B) 12m
C) 24 m
D) 36 m
Correct Answer: A
Solution :
Electric field due to a point charge \[E=\frac{1}{4\pi {{\varepsilon }_{0}}}\frac{q}{{{r}^{2}}}\] Electric potential due to a point charge\[V=\frac{1}{4\pi {{\varepsilon }_{0}}}\frac{q}{r}\] Dividing, \[\frac{E}{V}=\frac{1}{r}\] \[\Rightarrow \] \[r=\frac{V}{E}=\frac{3000}{500}=6\,metre\]You need to login to perform this action.
