Question

A negative point-charge $Q_1$ is 10 cm directly below a positive point-charge $Q_2$ as shown in (Figure 1). If $Q_1 = -2.0 \text{ nC}$ and $Q_2 = 5.0 \text{ nC}$, what is the magnitude of the net electric field created by the two charges at the point P? Express your answer using three significant figures. $E_{net} = 1.74 \times 10^4 \text{ N/C}$ What is the direction of the net electric field at the point P? Express your answer using three significant figures. Do NOT use the standard angle. Give your answer as a positive angle below the horizontal.

Step 1

99 x 10^9 N m²/C²), |Q₁| and |Q₂| are the magnitudes of the charges, and r₁ and r₂ are the distances from the charges to point P. Given: Q₁ = -2.0 nC = -2.0 x 10^-9 C Q₂ = 5.0 nC = 5.0 x 10^-9 C r₁ = 10 cm = 0.10 m r₂ = 5 cm = 0.05 m Calculate E₁ and E₂: E₁ = Show more…
