You made the net field for the 'q' point=0 Now all of the charges are in equilibrium so try making the net field = 0 on other charge; Q1 or Q2..

Well like charges repel each other while unlike charges attract each other. Q1 and Q2 are positive charges and q is placed between them. Now asses the resultant force on q by Q1 and Q2 separately in two cases: case 1 where q=+ve and case 2 where q=-ve. Draw FBD for both cases and see in which one q is at rest/eqlb. You will get your answer
