The long cylinder of radius R = 2 cm carries a charge evenly distributed throughout its volume with a density of 10 nC / m ^ 3. To determine the potential difference between the points spaced from the cylinder axis at a distance r1 = 1 cm and r2 = 3 cm. Plot the electric field intensity of the distance r from the cylinder axis.

Detailed solution shorthand terms, formulas, laws used in the decision, the withdrawal of the calculation formula and the response.
