Question

4. The diagram shows a rectangular array of four point charges and the forces three of the point charges exert on the fourth point charge ($q_4$). The fourth point charge is in static equilibrium under the influence of the three forces acting on it. If $\theta = 60^\circ$ and $F_3 = 10$ N, find the value of $F_1$. Note that the free-body diagram for the point charge $q_4$ is superimposed on the figure. Box your answer. Hint: Use the rectangular coordinate system included on the diagram to resolve $\vec{F_2}$ into its horizontal and vertical components.

4. The diagram shows a rectangular array of four point charges and the forces three of the point charges exert on the fourth point charge (q4). The fourth point charge is in static equilibrium under the influence of the three forces acting on it. If θ = 60^∘ and F3 = 10 N, find the value of F1. Note that the free-body diagram for the point charge q4 is superimposed on the figure. Box your answer.
Hint: Use the rectangular coordinate system included on the diagram to resolve F⃗2⃗ into its horizontal and vertical components.

Step 1

We have a point charge q in static equilibrium, which means the net force acting on it is zero. There are three forces acting on q, and we need to find the value of one of the forces, F, given that another force has a magnitude of 10 N and makes an angle of 60° Show more…

The diagram shows a rectangular array of four point charges and the forces three of the point charges exert on the fourth point charge (q). The fourth point charge is in static equilibrium under the influence of the three forces acting on it. If Î¸ = 60Â° and F = 10 N, find the value of F. Note that the free-body diagram for the point charge q is superimposed on the figure. Box your answer. Hint: Use the rectangular coordinate system included on the diagram to resolve F into its horizontal and vertical components. b+ F b+ VF
