Задача 30346.

Spherical capacitor formed by a sphere of radius R1 = 4 cm and R2 = 6cm, is charged to a voltage of 1 kV and off from the source. As far as the potential change point located at a distance of 5 cm from the center of the sphere, if the radius of the outer sphere to increase to R3 = 10cm? The outer sphere is grounded.

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