The electric field due to a very long straight and uniformly charged wire is given by the following expression: E = , where E is in N/C and r is the radial distance 2.0 from the wire (in meters). The radius of the wire is R = 0.005 m. a. Determine the magnitude (absolute value) of the electric potential difference between two points at the radial distances from the wire: r, = 0.20 m and r, = 0.40 m.
