At time t = 0, an electron (charge: -1.6 x 10-19 C; mass: 9.11 x 10-31 kg) is traveling with speed v0 = 27.5 x 106 m/s in the +x direction. A uniform electric field E (of magnitude 11.4 x 103 N/C and pointing in the +x direction) is then turned on.
(a) The electron begins to slow down once the electric field is turned on. Why?
(b) How far will the electron travel from its initial position at t = 0 before it stops?
(c) How long does it take the electron to return to its initial position?
