In a certain region of space, the electric field is E=x^2 i , where Eis in newtons per coulomb and x is in meters. Electric charges in this region are at rest and remain at rest. (a) Find the volume density of electric charge at x= m. Suggestion: Apply Gauss’s law to a box between x = 0.300 m and x = 0.300 m + dx. (b) Could this region of space be inside a conductor?
