Homework The Electric Field
Make sure to read pg. 453-459
1. Electric f______________________________ act over distances meaning there is a force
between two objects even if they are ___________________________________.
2. “fields” were developed by __________________________________________
3. An ________________________________________ goes out from every _____________________
4. If a second charge is placed near a first charge, it feels a ___________________________
exerted by the _______________________________________.
5. A _____________________________________ can be used to investigate an electric field
6. A n electric field ____________ is defined as the force exerted on a
_______________________ test charge placed at a ________________________________ divided
by the ______________________________________________ of the test charge
7. __________________________________________ where is the magnitude of the test charge
and is given an SI unit of _____________________________________________.
8. E describes the ___________________________________________________________creating the
electric field and not just the charge itself
9. For a single point charge e can also be written as: ___________________________
10. Using k = ¼  e0 then E = ___________________________________
11. Write notes from Electric fields and conductor here:
12. Look at example 16-6 The photocopy machine, Break down the approach so that
you can identify each of the givens in the problem to the equation E = F/q:
13. In Example 16-7, Use the equation E = k Q/r2 to solve the problem below, try
solving first then check with the book:
14. Example 16-8, before looking at the solution, draw out the vectors of E1 and E2,
then check with the book. Write below how you would go about solving for
acceleration. How does this compare to the book. In other words, analyze your
15. Write the problem solving techniques from pg 156 in your own words here:
16. Use these to solve Example 16-10 here (don’t just copy try and work it through:
17. Now read about Electric fields and Conductors on pg. 459, Read conceptual
Example 16-11and write an explanation in your own words here
18. Now try the following problems from pg. 469 and 470: # 21, 28, 32 and 36a (do
not do b). Show all diagrams, givens and units.
