Homework Statement



The potential difference between the accelerating plates of a TV set is about 20 kV. If the distance between the plates is 1.0 cm, find the magnitude of the uniform electric field in the region between the plates.



Homework Equations



V=ED so E=V/D where E is the electric field and D is the distance between the plates



The Attempt at a Solution



I am soooo confused. I swear I am just plugging in the numbers. since kv is 1000 v and cm is 1/100th of a m i did 20,000/.01 and that was wrong. I did this because they want the answer in N/C and i thought that conversion factor was right... any suggestions?

Your equation looks right to me. What did you get for a final answer? Did you include the units in your answer?
 
yes the units are already written after the equation. I got 2.0*10^6. after going over everything it looks right to me...
 
Yes, looks right to me too. Weird.
 
What's the answer supposed to be?
