1. The volume charge density ρv = ρ0⋅e−|x|−|y|−|z| exits over all free space. Calculate the total charge present . 2. A line charge with charge density equal to 10 nC/m is at x = 4, z = 3. A sheet of charge with surface charge density equal to −1 nC/m is at the xy - plane as shown in Figure 1. What is thw electric field at P(2, 3, 5) ? Figure 1:
