To solve this problem we first draw the diagram of given situation. question is where charge q is placed so that net force acting on it is zero.

If we consider the charge q is placed not on the line joining of other two charges then net force on it is never be zero.similarly ,if charge q is placed on the right or left side of Point B and point B respectively then net force due to other two charges are in same direction so net force on charge q cannot be zero.

Finally only one case is possible where charge q is placed between point A and B .

Since net force acting on charge q is zero , that is possible when force due to other two charges must balacnce each other ,after balncing force we get the value of location of charge q.

I try to explain all possible thoughts ,regarding this question if you need extra help please let me know in comment section.
