An electron has an initial velocity of 3.50 106 m/s in the x direction. It enters a uniform electric field = (400 N/C) , which is in the y direction. (a) Find the acceleration of the electron. (b) How long does it take for the electron to travel 10 cm in the x direction in the field? (c) By how much and in what direction is the electron deflected after traveling 10 cm in the x direction in the field? (To indicate direction, use negative for down and positive for upward.)
