question 12

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
