Задача 30303.

Point charge Q1 = 1 nC, Q2 = -2 nC, Q3 = 1nKl located on the plane lattice to a cell in the form of a square with side a = 0,1 m. The lattice sites, which are referred to the charges specified radius vectors r1 = (a, 0), r2 = (- a, a), r3 = (0, -a). The remaining nodes are no charges. Determine the strength and potential of the electric field at the points with the radius vector r = (a, -a).

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