A long thin wire, hundreds of meters long, carries a uniformly distributed charge of -7.2 microCoulombs per meter of length. Estimate the magnitude and direction of the electric field at points (a) 5.0 m and (b) 1.5m perpendicular from the center of the wire.

2. Relevant equations

Electric flux = Integral(E*dA)

Electric flux = Charge enclosed(Q) divided by Eo

Therefore, equating the two equations, you get:

Q/Eo = Integral(E*dA)

3. The attempt at a solution

The answer to part a(5.0m) is -2.6 X 10^4 N/C, but I do not know how they got that answer. I equated the two equations and solved for E, but I got 2.6 X 10^7 as an answer, which is wrong.
