  • A charge of +1.00C is at -3.00 m i and a charge of -1.00C is at the origin. In which direction does the electric field at +3.00 m i point?
  • What is the magnitude of the field at +3.00 m i?
  • There is a charge of -1.00C at +3.00 m I what is the electrostatic force on that charge due to the charges in (1)?
  • Suppose the charge at -3.00m i was doubled to +2.00C but the other charges remained unchanged, what would be the electrostatic force on the charge at +3.00 m i ?
