N ²2x²8. 21. Note that when x is in m, E will be in N/C. Electric the volume density of electric charge (in nC/m³) at x = 0.270 m. Suggestion: Apply Gauss's law to a box between x = 0.270 = (5.61 C.m² nC/m³ At a given region in space, the electric field is E = 5.68 x 103 charges in this region are at rest. Determine m and x = 0.270 m + dx.
