On thin wire ring of radius R = 8 cm evenly distributed charge q = 20 nC. Find strength and potential of the electric field on the axis of the ring as a function of the distance x from the center of the ring. Investigate cases of x = 0 and x many bolshii R. Construct graphs E (x) and f (x). Find the maximum value of the field intensity and the coordinates of the points at which the tension is maximized.

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