# Problem: A +16 nC charge is located at the origin.a. What is the strength of the electric field at the position (x,y)=(5.0cm, 0cm)?b. What is the strength of the electric field at the position (x,y)=(5.0cm, 5.0cm)?c. What is the strength of the electric field at the position (x,y)=(-5.0cm, 5.0cm)?

###### FREE Expert Solution

Electric field strength, E:

$\overline{){\mathbf{E}}{\mathbf{=}}\frac{\mathbf{k}\mathbf{q}}{{\mathbf{r}}^{\mathbf{2}}}}$

r = sqrt(x2 + y2)

a.

r  = sqrt (52 + 02) = 5.0 cm.
