A positive point charge (q) is at the center of a circle with a radius of $$r=4.42\mathrm{m}$$ as shown in the figure. Given $$?\mathrm{q}?=268\mathrm{nC}$$; and $$?=39.0^{?}$$. What is the $$\mathrm{x}$$-component (unit in $$\mathrm{N}/\mathrm{C}$$ ) of the electric field at position P? As shown in the figure, a positive point charge is located at the center of a square ABCD. E, F, G, H are located at the middle of each side. What is the direction of the electric freld at position $$F$$ ? Directed toward the left Directed toward the right Directed upwards Directed downward Directed toward up-left Directed toward up-right Directed toward down-left Directed toward down'right
