  1. A charge Q1 = +9μC is located at the origin and a second charge Q2 = -4μC is placed at x = 8 m. What will be the force (magnitude and direction) if you place a +16 μC charge midway between the Q1 and Q2? 1?= 10^-6, Coulomb’s constant ?=9.0*10^9 N*m^2/C^2

  2. Calculate the net electric field (magnitude and direction) at x = 10 m due to the two charges Q1 and Q2 given above. What is the force on an electron if it is placed at this point (i.e. x = 10 m)? e = 1.602*10^-19 C

  3. Find the point on the x-axis where the electric field is zero.
