Happy Birthday Richard and Eric! (:

Hello everyone, Rojuane here for another scribe.

Today we went over the test questions that we finished the Electric Force worksheet.
The answers are:
1) FE= 3.6x10^10 N
2. a) FG=7.8x10^-47 N
b) FE=8.8x10^-8 N
3. Ne 2.5x10^19 N
4. Q=1.76x10^8 C
5. a) FE 1.76x10^-15 N [towards -2x10^-12 C charge]
b)a=2.6x10^11 m/s^2

Then we were given questions and pages to read from the green textbook. If you didn't catch the page numbers they are:
pg. 415-419, 1-5 p. 420 (answers from back of textbook)
and questions 1,9,10,16 (Sorry, you have to do those on your own)
DON'T FORGET to hand in those four questions for marks for tomorrow class!

Next Scribe will be, SHELLY :)
