and we went over problem 8 to 11 in the class.
8.v=2.1 . 10^5 m/s
f=5.6 . 10^-13 N
B=f/qv
B=5.6 . 10^-13/(1.6 . 10^-19)(2.1 . 10^5)
B=16.6T[left]
9.v=8.6 . 10^4m/s
B=1.2T
F=?
F=Bqv
F=(1.2 )(1.6 . 10^-19)(8.6 . 10^)
F=1.7 . 10^-14N[E]
10.v=5.0 . 10^5m/s
F=4.0 . 10^-6N
B=F/qv
B=4.0 . 10^-6/(1.6 . 10^-19)(5.0 . 10^5)
B=5. . 10^7T [out of the page]
11.v=2.0 . 10^6m/s
B=5.0 . 10^-2T
F=4.8 . 10^-14N
q=?
q=F/Bv
q=4.0 . 10^-14/(5.0 . 10^-2)(2.0 . 10^6)
q=4.8 . 10^-19C
Miss Kozoriz explain a bit The Mass of an Electron, we read the Green book from page 536-541 for some basic formulas.
We got home work for the Worksheet "Moving Charges" for problems 12-16 and Review Chapter 27. And we have test on Tuesday. Have a nice weekend and prepare for the test.
