The Figure shows two square arrays of charged particles. The squares, which are centered on point P, are misaligned. The particles are separated by either d or d/2 along the perimeters of the squares. What are the magnitude and direction of the net electric field at P?

Four charged particles are located at the corners of a square of side length a = 30.0 cm, as shown. The unit charge q =+10.0μC. (a) What is the magnitude and direction of the electric field at the lower left corner?

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.

In the figure the four particles form a square of edge length a = 5.00 cm and have charges q1 = 9.04 nC, q2 = -21.0 nC, 93 = 21.0 nC, and 94 = -9.04 nC. What is the magnitude of the net electric field produced by the particles at the square's center?

The drawing shows a positive point charge q1, a second point charge q2 that may be positive or negative, and a spot labeled P, all on the same straight line. The distance d between the two charges is the same as the distance between q1 and the spot P. With q2 present, the magnitude of the net electric field at P is twice what it is when q1 is present alone. Given that q1 = 0.50 μ C, determine q2.

The figure below shows three small, charged beads, all lying along the horizontal axis. Bead A, at left, has a 6.55 nC charge. Bead B has a 1.64 nC charge and is 3.00 cm to the right of A. Bead C has a -2.75 nC charge and is 2.00 cm to the right of B. What is the magnitude (in N/C) of the electric field at a point 2.00 cm to the right of A?

In the figure particle 1 (of charge +7.58 mC), particle 2 (of charge +7.58 mC), and particle 3 (of charge Q) form an equilateral triangle o edge length a. For what value of Q (both sign and magnitude) does the net electric field produced by the particles at the center of the triangle vanish? Number i Units C-m

In the figure particle 1 (of charge +5.43 mC), particle 2 (of charge +5.43 mC), and particle 3 (of charge Q) form an equilateral triangle of edge length a. For what value of Q (both sign and magnitude) does the net electric field produced by the particles at the center of the triangle vanish?

Figure (a) shows three plastic sheets that are large, parallel, and uniformly charged. Figure (b) gives the component of the net electric field along an x axis through the sheets. The scale of the vertical axis is set by Es = 5.4 × 105 N/C. What is the ratio of the charge density on sheet 3 to that on sheet 2?
