Four charges Q1
Four charges Q1, Q2, Q3 and Q4 of same magnitude are fixed along the x axis at x = −2a,−a, +a and +2a, respectively. A positive charge q is placed on the positive y axis at adistance b > 0. Four options of the signs of these charges are given in List I. The directionof the forces on the charge q is given in List II. Match List I with List II and select the correct answer using the code given below the lists.
