Задача 30415.

A positively charged particle, the charge of which is equal to the elementary charge, has passed the accelerating potential difference of 60,000 V and flies to the nucleus of the lithium atom, the charge of which is equal to three elementary charges. What is the smallest distance a particle can approach the nucleus? The initial distance of the particle from the nucleus can be considered almost infinitely large.

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