Задача 31262.

The electrostatic field is created by a ball of radius R = 10 cm, uniformly charged with a bulk density of 20 nC / m ^ 3. Determine the potential difference between the points lying inside the sphere at distances R 1 = 2 cm and R 2 = 8 cm from its center.

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