Dipolar Electric Field

The image below shows an electric field with an orange negative source charge on the left and a blue positive source charge on the right, the two source charges are equal in magnitude. This is called a dipolar electric field. Now imagine that you are placing test-protons at positions along the three lines shown in the image: A (left), B (middle) & C (right).

Questions

Please answer the questions below.

Do you think that the test-protons along A, B and C will all follow the same path? Or, do you think that the trajectories of charges starting at A, B & C will be different? Explain your reasoning.

Below, sketch the paths you think charges placed on these lines would follow. 

Note: Draw your sketch in the sketchpad below
