It make sense if the question is asking which one is the incorrect force since my diagram contain all the arrows except B..

SUMMARY
The discussion centers on the application of Coulomb's law to determine the forces between two charges, +Q and -Q, positioned 1 cm apart. The conclusion is that the magnitude of the force remains the same regardless of the charge's polarity, as the question specifically asks for magnitude, not direction. Participants clarify that the vector sum of forces must be considered, emphasizing that the forces in directions A, C, and D are relevant for understanding the problem. The answer to the question is confirmed as B, indicating the forces' magnitudes do not change despite the charge's alteration.

and for this question
Question:Two charges of +Q are 1 cm apart. If one of the charges is replaced by a charge of –Q, the magnitude of the force between them is
Ans: the same
Won't they either get attracted or repelled? then , the magnitude will change isn't it?

For the first question, you already know the forces are in directions A, C and D.
Form the vector sum of forces A and C, then compare it to the size of the force in direction D.
For the second question, just apply Coulomb's law to the 2 situations to compare the magnitudes of the forces. It doesn't ask anything about the direction.
