Unformatted text preview: 4B Homework 03 Question 1 In Figure 23-29, a proton is a distance d /2 directly above the center of a square of side d . What is the magnitude of the electric flux through the square? ( Hint : Think of the square as one face of a cube with edge d .) Figure 23-29 Number 3.01E-9 Units N·m^2/C The number of significant digits is set to 3; the tolerance is +/-2% *Question 2 The figure 23-32 shows a closed Gaussian surface in the shape of a cube of edge length 2.62 m. It lies in a region where the electric field is given by = (1.70 x + 5.30) + 6.32 + 8.22 N/C, with x in meters. What is the net charge (in Coulombs) contained by the cube? Figure 23-32 2.71E-10 C The number of significant digits is set to 3; the tolerance is +/-2% *Question 3 Space vehicles traveling through Earth's radiation belts can intercept a significant number of electrons. The resulting charge buildup can damage electronic components and disrupt operations. Suppose a spherical metallic satellite 1.2 m in diameter accumulates -3.1 µC of charge in one orbital revolution. components and disrupt operations....
