| 2.1 Sources of electric ( E-) fields are electric charges, measured in coulombs (C). Various space distributions of charge are: line, surface, and volume distributions; these are respectively described by density functions ? ? (C/m), ? s (C/m 2), and ? v (C/m 3). Find the total charge on the x axis from 0 to 10 m if ? ? = 3 x 2 ( ?C/m). |

| 2.2 Given ? ?( x, y, z) = 2 x + 3 y - 4 z (C/m), find the charge on the line segment extending from (2, 1, 5) to (4, 3, 6) |
