An electron is initially moving in the +z direction, with a speed v=2.54x105 m/s at z=0. In the regionbetween z=+1.50 cm and z=+2.50 cm, there is a uniform electric field of magnitude 4.10x104 N/C in the+x direction. Outside that region (z +2.50 cm) the electric field is zero. Find thevelocity of the electron after it leaves the field region (z > +2.50 cm.)
