Solution to task 349 from Chertov´s for extramural stud

349. The electric field is created by an infinite charged straight line with a uniformly distributed charge (τ = 10 nC / m). Determine the kinetic energy T2 of an electron at point 2, if at point 1 its kinetic energy is T1 = 200 eV (Fig. 30).
