A positively charged particle is held at the center of a spherical shell. The figure gives the magnitude E of the electric field versus radial distance r. The scale of the vertical axis is set by E, = 11.0 x 107 N/C. Approximately, what is the net charge on the shell? Assume rs = 2 cm. Number i 6.54E-6 E (107 N/C) E 0 Units rs N/C 2r, 3r, r (cm) 4r, 5r,

1 2 3 A В E The figure above shows four very thin parallel planes of charge with equal separation between them. The charge density on plate 1 is 2 nC/m2. The charge density on plate 2 is -5 nC/m2. The charge density on plate 3 is 4 nC/m2. The charge density on plate 4 is 3 nC/m2. Your answers for the electric field must include the correct sign. We choose positive electric field along the positive x-direction. What is the Electric Field at point D? (in units of N/C) N/C Submit Answer Tries 0/2

Two infinite nonconducting plates are parallel to each other, with a distance d = 12.0 cm between them. Each plate carries a uniform charge distribution with the surface charge density o = 4.28 μ C/m². What is the magnitude of the electric field at point R (with r = 17.0 cm)? ச 16 R 22 0.00 N/C 4.84 x 105 N/C O 5.80 x 105 N/C 3.87 x 105 N/C 3.39 X 105 N/C X

The figure shows a closed Gaussian surface in the shape of a cube of edge length 2.50 m. It lies in a region where the electric field is given by E = (1.60x +3.08)i +7.77 +5.70 kN/C, with x in meters. What is the net charge contained by the cube? Number i 1.2e-10 Units C x
