Two point charges Q and +q (where q is positive) produce the net electric field shown at

Question:

Two point charges Q and +q (where q is positive) produce the net electric field shown at point P in Fig. E21.36. The field points parallel to the line connecting the two charges.

(a) What can you conclude about the sign and magnitude of Q? Explain your reasoning.

(b) If the lower charge were negative instead, would it be possible for the field to have the direction shown in the figure? Explain your reasoning.
