today's class

Hey guys ... almost forgot to blog today =|

In today's class we went over the questions from the booklet electric fields. ( questions 1-4)
After that, we also went over the three questions 1-3 from the electric fields worksheet.

For today's homework , we have to do questions 4-10 from the electric fields worksheet

use the formula
N=q/e

e= 1.6x10^-19

( check the blog for today's lesson)

And last but not least, we were given the physics review for the upcoming exam.

Well, that's all what we did today =)
( sorry for blogging so late =| )
