Задача 31614.

When the sphere is irradiated with ultraviolet rays, electrons with an initial velocity of 10 ^ 6 m / s are pulled from its surface. As a result, the ball acquires a positive charge. Determine the limiting charge of the ball. The radius of the ball is R = 1 cm.

A detailed solution with a brief record of the condition, formulas and laws used in the solution, the derivation of the calculation formula and the answer.
If you have any questions about the solution, write. I try to help.
