  1. Coulomb’s Law of Electrostatic Attraction Using Charges and Forces PreAP Physics

  2. Electrostatic Interaction Coulomb’s Law charge on object 1 in C charge on object 2 in C Force in N Distance between objects in m Coulomb’s Constant: 8.99 x 109 N·m2/C2

  3. Example 1. A +5 µC object and a - 20µC object are 6 m apart. Calculate the force between them.

  4. Example 2. A -8 µC object experiences an attractive force of 4 x 10-7 N towards a +1.4 µC object. How far apart are the objects.-

  5. Coulomb’s Law of Electrostatic Attraction Part 2: Examples 3 and 4

  6. Example 3: A +5 µC object and a +20µC object are 6 m apart. Where could we place a -1 µC object as that it would remain stationary?

  7. Example 4: A +3 nC object and a +18 nC object are 7 m apart. A -6 nC object is located between them, 2 m from the +3 nC object. Calculate the force on the -6 nC object.
