Homework Statement
A very long, straight wire has charge per unit length 1.47×10^10
At what distance from the wire is the electric field magnitude equal to 2.57 N/C
Homework Equations
E = lambda / (2*pi*E_o*r)
E_o = 8.85*10^-9
The Attempt at a Solution
2*pi*E_o*E / lambda = r
Is this correct so far?
