There are two possibilities depending on where A is.

If**A is on one side of both P and Q**, then net force can be zero, only if one charge is higher and another smaller and **both are oppositely charged**. It will be possible when the charges A, P and Q are collinear.

Net force on A will be zero, if** A is in between P & Q** and they are** both of the same polarity**. ie., both positive or both negative. Here the to forces will be in opposite directions. Assuming that A, P, and Q are on the same straight line. Here is it possible that on e charge is higher than the other.

If

Net force on A will be zero, if
