Consider a line of charge that extends along the x axis from x = -4 m to x = +4 m.  The line of charge has a constant linear charge density equal to 3.9 nC/m (note the nano).  Calculate the magnitude of the electric field due to this charge at (0, 6 m), in N/C.  Use k = 9 x 109 N m2 / C2.  The resulting integral is solved with trigonometric substitution, so solve the integral using a computer if you don't know how to do this. (Please answer to the fourth decimal place - i.e 14.3225)
