In this problem, we need to use the equation for the Electric field:

$\overline{){\mathbf{E}}{\mathbf{=}}\frac{\mathbf{k}\mathbf{q}}{{\mathbf{r}}^{\mathbf{2}}}}$, where **k** is Coulomb's constant, **q **is the charge, and **r **is the distance from the point charge.

In this problem, the length of the rod, L = 10cm = 10 × 10^{-2} m

The charge on each glass rod is, q_{1} = q_{2} = 15 × 10^{-9} C

The distance between the two rods is x = 4.0 cm = 4.0 × 10^{-2} m

In this case, the electric field strength at point P located at a distance x from the center of ros along its perpendicular bisector is expressed as:

$\overline{){\mathbf{E}}{\mathbf{=}}{\mathbf{k}}\frac{\mathbf{q}}{\mathbf{x}\sqrt{{\mathbf{x}}^{\mathbf{2}}\mathbf{+}{\mathbf{\left(}{\displaystyle \frac{\mathbf{L}}{\mathbf{2}}}\mathbf{\right)}}^{\mathbf{2}}}}}$

Two 10 cm -long thin glass rods uniformly charged to +15nC are placed side by side, 4.0 cm apart. What are the electric field strengths E_{1}, E_{2}, and E_{3} at distances 1.0 cm, 2.0 cm, and 3.0 cm to the right of the rod on the left, along the line connecting the midpoints of the two rods?
