Задача 30970.

An electron flies into a uniform electric field with an initial speed V0 = 10^7 m/s at an angle of 60° to the X axis, perpendicular to the lines of force of this field, and after some time crosses this axis again. Field strength E = 10^4 V/m. Determine the distance between the points at which the electron crossed the X-axis, and find the speed of the electron at the moment it crossed the X-axis again.
