Задача 30881.

A metal sphere of radius R = 5 cm is charged to a potential of 300 V. The ball is placed in the center of the spherical shell having a relative dielectric constant e = 5. Inner shell radius R1 = 15cm, outer radius R2 = 25 cm. Find poverhnoctnye density and related charges on the inner and outer shell poverhnoctyah.

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