2 Field from continuous line segment (25 pts total ) y X=-a X X+XIX X=VG X Figure 2: Continuous line of constant charge per length > > 0 running from x = 0 to x = b along r-axis, and point P at location (x = -a, y = 0). 2.1 Field direction (5 pts) Sketch on the figure the direction of the electric field at the point labeled P, assuming > > 0. 2.2 Limiting case (6 pts) For the case when a b, the electric field at P will begin to resemble that of which charge distribution? Field resembles that of a Use your answer to the above question to give an approximate estimate for the electric field at point P when a b. When a b, E(P) ~
