Trying out the google "poll" function

This is rather primitive, but might be fun.  Take a look at the left sidebar, where a fundmentals multiple choice question masquerades as a poll.  Feel free to vote... your response is anonymous.  I can't figure out how to format equations properly in the poll.  The text editor won't allow html tags.  Any thoughts?

I'll leave the poll up until I get a few votes.  Then, if there's disagreement about the answer, I'll write a post about it.

UPDATE -- Okay, I screwed up the initial poll question.  It asks for magnitude and direction of the electric field, and I left off the direction choices.  Apologies.
