Задача 31525.

Two electrons are moving in one direction along a straight line with the same modulus at 10 ^ 4 m / s. Find the magnetic field strength at a distance charges between 4 * 10 ^ -8 cm. The point for which is determined by the magnetic field strength is on the perpendicular to the middle of the path at a height of 3 * 10 ^ -8 cm.

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.
