Задача 30734.

The electrostatic field is generated by two infinite parallel planes, uniformly charged with surface charge density of 0.3 and 0.7 SCLC / m ^ 2. To determine the field strength between the plates and the plates out. Find the potential difference between the plates when the distance between the two 4 cm. To graph intensity along a line perpendicular to the plates.

Detailed solution with a short recording conditions, laws and formulas used in the decision, the withdrawal of the calculation formula and the answer.
If you have any questions about the decision to write. I try to help.
