Use the Picture for the Next Problem $\times$ 10^-14 Kg,speed V = 10⁵ M/s,the Electric Field Strength E

Multiple Choice

Use the picture for the next problem. A negatively charged particle moving with speed v enters a region of uniform electric field E.
-If the charge q = 1 nC,mass m = 1 $\times$ 10^-14 kg,speed v = 10⁵ m/s,the electric field strength E = 2 $\times$ 10⁵ V/m,and width,w,of the electric field is 0.2 m,what is the speed of the particle when it emerges from the other side?

A) 1.0 $\times$ 10⁵ m/s
B) 4.0 $\times$ 10⁴ m/s
C) 1.08 $\times$ 10⁵ m/s
D) 1.4 $\times$ 10⁵ m/s
E) 1.8 $\times$ 10⁵ m/s
