A point charge q1 = -4. 00 nc is at the point x = 0. 60 m, y = 0. 80 m , and a second point charge q2 = +6. 00 nc is at the poin

The net electric field is the vector sum of the components of the electric

field produced by the two charges.

The values of the magnitude and direction of the net electric field at the origin (approximate values) are;

  • 131.6 N/C
  • 12.6 ° above the negative x–axis

<h3>How are the net electric field magnitude and direction calculated?</h3>

The possible questions based on a similar question posted online are;

(a) The net electric field at the origin.

The electric field due to charge q₁ is given as follows;

\vec E_{1x} = \mathbf{ \dfrac{1}{4 \cdot \pi \cdot \epsilon_0} \cdot \dfrac{q_1}{\vec{r}^2_2}}

Which gives;

\vec{E}_{1x} =\mathbf{ \dfrac{\left(9 \times 10^9 \, N \cdot m/C^2 \right) \cdot \left(-4 \, nC \times \dfrac{10^{-9}C}{1 \, nC} \right)}{\left(1 \, m \right)^2}} \cdot cos\left(arctan\left(\dfrac{0.8}{0.6} \right) \right) =-21.6 \, N/C

\vec{E}_{1y} = \mathbf{\dfrac{\left(9 \times 10^9 \, N \cdot m/C^2 \right) \cdot \left(-4 \, nC \times \dfrac{10^{-9}C}{1 \, nC} \right)}{\left(1 \, m \right)^2}} \cdot sin\left(arctan\left(\dfrac{0.8}{0.6} \right) \right) = 28.8 \, N/C

Which gives;

\vec{E}_1 = \mathbf{21.6 \, N/C  \cdot \hat x +  28.8 \, N/C \hat y}

\vec{E}_{2x} = \dfrac{\left(9 \times 10^9 \, N \cdot m/C^2 \right) \cdot \left(6.00 \, nC \times \dfrac{10^{-9}C}{1 \, nC} \right)}{\left(1 \, m \right)^2} = 150 \, N/C

Therefore;

\vec  {E} = \left[ 21.6 \, N/C - 150 \, N/C \right] \left( \hat x \right) + \left(28.8 \, N/C \right) \left( \hat y \right)

\vec  {E} = \mathbf{\left( -128.4 \, N/C  \right) \left( \hat x \right) + \left(28.8 \, N/C \right) \left( \hat y \right)}

The magnitude of the net electric field is therefore;

E = \sqrt{(-128.4^2 + 28.8^2)} ≈ 131.6

  • The magnitude of the net electric field at the origin is E ≈<u> 131.6 N/C</u>

(b) The direction of the net electric field at the origin.

  • The \ direction \ is \ arctan \left(\dfrac{28.8}{-128.4} \right) \approx \underline{ 12.6^{\circ}} \ above \ the \ negative \ x-axis

Complete the equilibrium reactions which are pertinent to an aqueous solution of ag2co3. physical states are optional.
nevsk [136]

The equilibrium reactions pertinent to an aqueous solution of Ag2CO3 in which physical states are not considered is:

\mathbf{Ag_2CO_{3 \ (s)} \rightleftharpoons 2Ag^{+}_{(aq)} + CO_3^{2-}}

<h3>What are equilibrium reactions?</h3>

An equilibrium reaction is a chemical reaction process in which the reactants remain in a steady and stable condition both previously(reactant) and after the reaction is completed(product).

A reaction is considered to be at thermodynamic equilibrium when a reaction meets all three categories of equilibrium;

  • Equilibrium of temperature
  • Equilibrium in the chemical reaction.
  • Equilibrium with the surrounding factors like pressure.

The equilibrium reactions pertinent to an aqueous solution of Ag2CO3 is:

\mathbf{Ag_2CO_{3 \ (s)} \rightleftharpoons 2Ag^{+}_{(aq)} + CO_3^{2-}}

Appellate court judges
damaskus [11]
Appellate court judges do not re-try cases, and they do not hear new evidence. Rather, they review decisions made by the trial court. They are usually limited to reviewing only the arguments that were made in the trial court and raised by the parties.
