A charged particle in an electric field "E" is acted upon by a force F = q *E, where "q" is the magnitude of the particle's electric charge. Consider the situation where an electron (electric charge ?e ? ?1.602 10^?19 C, mass m_e ? 9.109 10^?31 kg) enters the electric field from the direction of the negative x-axis at the time t = 0 at the point x = 0 with an initial velocity v0 = (100 m/s)?i. The electric field is greater than zero only in the range x > 0. Forces other than those caused by the electric field can be ignored.

How far from the entry point does the electron re-emerge from the electric field if the electric field depends on time as follows:
