Ch.
16 Electric Charge and Electric Field

Question: 17

Problems:

10 (also discuss why we aren't electrostatically attracted to one another since the electrostatic force is so much larger than the gravitational force)

15 (find the magnitude and direction for each)

20 (what sign is the third charge?)

37 Triangle geometry. Remember that the internal angles are all 60.

38 This is also similar to the arrangement in Question 17.

52 How to just balance gravity

53 Getting a feel for the number of electrons
