A) the electric field at point O is \[\frac{q}{8\pi {{\varepsilon }_{0}}{{R}^{2}}}\] directed along the O to A.
B) the magnitude of the force between the charges at C and B is \[\frac{{{q}^{2}}}{64\pi {{\varepsilon }_{0}}{{R}^{2}}}\]
C) the potential at O is zero.
D) the potential at point O is \[\frac{q}{12\pi {{\varepsilon }_{0}}R}\]
Correct Answer: C
Solution :
\[{{V}_{0}}=\frac{(q/3)\,+(q/3)-(2q/3)}{4\pi {{\varepsilon }_{0}}R}=0\]You need to login to perform this action.
