A point charge q1=−4.00nC is at the point x=0.600 meters, y=0.800 meters, and a second point charge q2=+6.00nC is at the point x=0.600 meters, y=0.Calculate the magnitude E of the net electric field at the origin due to these two point charges.
Express your answer in newtons per coulomb to three significant figures.

Best ResponseYou've already chosen the best response.2here you have to compute a vector sum, in other words the resultant electric field, at the origin of the coordinate system is given by the subsequent formula: \[\Large {\mathbf{E}} = {{\mathbf{E}}_{\mathbf{1}}} + {{\mathbf{E}}_{\mathbf{2}}} =  \frac{{k\left {{q_1}} \right}}{{x_0^2 + y_0^2}}{{\mathbf{r}}_{\mathbf{1}}}  \frac{{k{q_2}}}{{x_0^2}}{{\mathbf{r}}_{\mathbf{2}}}\] where r_1 and r_2 are the subsequent vectors: dw:1435745839643:dw

Best ResponseYou've already chosen the best response.2now, developing that vector equation we get, the subsequent scalar equations: \[\Large \begin{gathered} {E_x} = \frac{{k\left {{q_1}} \right}}{{x_0^2 + y_0^2}}\frac{{{x_0}}}{{\sqrt {x_0^2 + y_0^2} }}  \frac{{k{q_2}}}{{x_0^2}} \hfill \\ \hfill \\ {E_y} =  \frac{{k\left {{q_1}} \right}}{{x_0^2 + y_0^2}}\frac{{{y_0}}}{{\sqrt {x_0^2 + y_0^2} }} \hfill \\ \end{gathered} \] where E_x and E_y are the components x, y respectively of the resultant vector field, and x_0=0.6 meters, and y_=0.8 meters
