An Electron Is Fired Through a Pair of Deflection Plates,which $\times$

An electron is fired through a pair of deflection plates,which produce a 2.00 cm long region with an electric field of 4000 N/C perpendicular to the electron's initial velocity.If the initial speed of the electron is 1.00 $\times$ 10⁷ m/s,what angle will its new velocity make with the direction of the original velocity?

A) 14 $^{\circ}$
B) 8.0 $^{\circ}$
C) 5.5 $^{\circ}$
D) 4.6 $^{\circ}$
E) 1.4 $^{\circ}$
