Task 31565.
An infinite plane is negatively charged with an areal density of 35.4 nKl / m ^ 2. At the direction of the field lines created by a plane flying electron. Determine the minimum distance at which the electron can approach the plane, if at a distance of 5 cm, he had a kinetic energy of 80 eV.
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.
