Charge Q₁ = 6.0 nC is at the position (0.2 m, 0.2 m), charge Q2 = -2.0 nC is at (-0.4 m, 0.2 m), and Q1 charge Q3 = 4.0 nC is at (-0.2 m, -0.4 m). (a) What is the net electric field at the point (0, 0)? Your work must include the following. Create sketch with a coordinate system that shows all source charges and electric field vectors from each source charge. The sketch should be at least a half a page. Show ŕ and ŕ for each source charge both on the image and in algebraic form. Show the electric field for each source charge in unit vector form. Show the net electric field in unit vector format. Show the magnitude of the net electric field.

The electric field at point P is 9.3 x 1020 N/C @ 343°. What is the angle of the force experienced by a proton if it is placed at point P. Express your answer in degrees.

A 10 nC charge generates an electric field within an isolated chamber. At a point a distance d  meters away from the charge, the electric field is measured to be 4 N/C. Determine d in meters. Use k=9 x109  for the electric constant. (nC to C in final answer)

A charge Q1=9 uC is place on the y axis at -3 m, and charge Q2=-16uC is place at the x axis at 4m. What is the magnitude of the net electric field at the origin

Suppose you design an apparatus in which a uniformly charged disk of radius R is to produce an electric field. The field magnitude is most important along the central perpendicular axis of the disk, at a point P at distance 2.60R from the disk (see Figure (a)). Cost analysis suggests that you switch to a ring of the same outer radius R but with inner radius R/2.60 (see Figure (b)). Assume that the ring will have the same surface charge density as the original disk. If you switch to the ring, by what part will you decrease the electric field magnitude at P? Number i Units (a) (b)
