The figure shows a rectangular array of charged particles fixed in place, with distance a = 31.0 cm and the charges shown as integer multiples of q1 = 2.65 pC and q2 = 7.46 pC. With V= 0 at infinity, what is the net electric potential at the rectangle's center? +29₁ +492 39₁ +492 +291

The drawing shows two situations in which charges are placed on the x and y axes. They are all located at the same distance of 5.40 cm from the origin O. For each of the situations in the drawing, determine the magnitude of the net electric field at the origin. -5.0 μC I -3.0 μ.C +2.0 μC (a) +4.0 μ.C +1.0 μC +6.0 μC (b) -1.0 μC

Three point charges, −4Q, −2Q, and +5Q, are shown in the figure where Q = 95 μC. The -4Q point charge is located in the center of the cube as shown, and two other charges are on the outside. (a) What is the electric flux through each face of the cube? face N•m²/C (b) What is the electric flux through the whole cube? cube N•m²/C +5Q (d) Gauss's law would to find the electric field on the surface of the cube because O you don't know the surface area of the cube O the electric field isn't uniform on its surface O the cube is ticklish and that would be funny (-4Q) (c) Moving the -4Q charge away from the center of the cube would change the electric flux through ... O each face of the cube O the whole cube O each face and the whole cube -2Q

What will be the electric field strength at 100 m away from an isotropic source? The source is transmitting 5 kilowatts of power
