3. two charges are on the x axis: 4.00 C at x = 0.100 m and -3.00 C at x = 0.200 m. Draw a diagram of the situation and determine the magnitude of the electric field (in N/C) at a point on the x axis at x = 0.300 m.

4. for the situation in the previous question, what is the direction of the electric field at x = 0.300 m?

5. for the situation in the two previous questions, what is the force (in N) on a charge of - 4.00 C which is placed on the x axis at x = 0.300 m?
