1. Two charges of +3.0E-6C are placed, 0.4m from each other.  What is the force felt by each charge? (answer)
2. Two charges of -3.0μC are placed, 0.2m from each other.  What is the force felt by each charge? (answer)
3. A charge of +2.0μC is placed at the origin.  Another charge of -4.0μC is placed at 0.4m along the X axis.  What is the force felt by the +2.0μC charge?  Make sure you indicate direction. (answer)
4. A charge of +6.0E-9C is placed at the origin.  Another charge of +2.1E-9C is placed at 0.1m along the Y axis.  What is the force felt by the 2.1E-9C charge?  Make sure you indicate direction. (answer)
5. Three charges are placed along the X axis.  A -3.4μC charge is placed at -0.2m.  A -1.2μC charge is placed at the origin and a +4.0μC charge is placed at 0.3m.  Find the magnitude and direction of the net force the -3.4μC charge.  Find the magnitude and direction of the net force on the other two charges. (answer)
6. Three charges are placed along the Y axis.  A -2.0E-6C charge is placed at 0.1m.  A +4.1E-6C charge is placed at the origin and a +2.1E-6C charge is placed at -0.1m.  Find the magnitude and direction of the net force on each charge. (answer)
7. Three charges are placed in a straight line.  Charge A has a magnitude of +4E-9C.  0.1m to the right of charge A, charge B has a magnitude of +3.0E-9C.  0.2m to the right of charge B, charge C has a magnitude of -1.4E-9C.  Find the magnitude and direction of the net force on each charge. (answer)
8. Three charges are placed in a right triangle configuration.  The charge at the origin has a magnitude of +2.0μC.  Another charge located at 0.1m on the X axis has a magnitude of -2.2μC.  Lastly, a charge located at 0.2m on the Y axis has a magnitude of -3.0μC.  Find the net force on the charge located at the origin.  Don't forget to find the direction. (answer)
9. Three charges are placed in a right triangle configuration.  The charge at the origin has a magnitude of +3.0μC.  Another charge located at 0.1m on the X axis has a magnitude of +4.0μC.  Lastly, a charge located at 0.2m on the Y axis has a magnitude of +5.0μC.  Find the net force on the charge located at the origin.  Don't forget to find the direction. (answer)
10. Three charges are placed in a right triangle configuration.  The charge at the origin has a magnitude of +1.0E-9C.  Another charge located at 0.05m on the X axis has a magnitude of +2.0E-9C.  Lastly, a charge located at 0.01m on the Y axis has a magnitude of -4.0E-9C.  Find the net force on the -4.0E-9C charge.  Don't forget to find the direction. (answer)
