  9. Coulomb’s Law al l’experiment Make all in the same way Standard red charges

  10. 1: How’s force related to the amount of charge???

  11. 1: How’s force related to the amount of charge???

  12. 1: How’s force related to the amount of charge???

  13. 2: How’s force related to the arrangement of charge???

  14. 2: How’s force related to the arrangement of charge???

  15. 3: How’s force related to theseparationof charges???

  16. 3: How’s force related to theseparationof charges???

  17. 3: How’s force related to theseparationof charges???

  18. Experimental results: RED charges (and is repulsive !!) Check: Blue-Blue follows the same rules!

  19. Experiment: Making a standardBLUE charge?

  20. Experiment: Making a standard BLUE charge?

  21. Experiment: Making a standard BLUE charge? adjust Quntil Then the amount of blue charge is the same as the amountQS of red

  22. The semi-final analysis Red or blue types

  23. The final analysis Red or blue types

  24. Conventions: is red kind of charge is blue kind of charge means repulsive means attractive

  25. Unit of charge = Coulomb How much What type (Blue)

  26. Experiment →

  27. Vector nature of forces!!

  28. Vector nature of forces!!

  29. Vector nature of forces!!

  30. Vector nature of forces!!

  31. Vector nature of forces!!

  32. Vector nature of forces!!

  33. Vector nature of forces!!

  34. Plug-in example:

  35. Nimitz-class super carrier’s weight? Displacement ≈ 102,000 tons ≈ 9×108 N Force between two 1-C Charges separated by One meter Weight of ten of these aircraft carriers ≈

  36. Lesson: a Coulomb is a lot of charge! How much charge (Q) required to provide F = 1 N at a separation of 1 cm ? Next page!

  37. Vector superposition:

  38. Vector superposition:

  39. Vector superposition:

  40. Number example 1.50 cm Net force on this charge? 2.00 cm

  41. A) Figure force due to +3.0 mC charge 1.50 cm

  42. B) Figure force due to -2.5 mC charge 2.00 cm

  43. All the forces acting on our charge of interest: C) Net? Add them up 1.50 cm 96 N 204 N
