A long, thin, straight wire of length 1.3 m has a positive charge 4.1 × 10-8 C distributed uniformly along it. The electric field created by this wire at a radial distance 3.2 cm has a magnitude of
I think I need to use E= q/(4πr^2ε) but I don't know what to do with 1.3 m.
The Attempt at a Solution
E= 4.1E-8/(4π(.032^2)(8.85e-12) =360023.43
