Four charge Q 1 , Q 2 , Q 3 , and Q 4 , 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 a distance b > 0. Four options of the signs of these charges are given in List-I. The direction of the forces on the charge q is given in List- II Match List-1 with List-II and select the correct answer using the code given below the lists.
List-I | List-II | ||
(P) | Q1, Q2, Q3, Q4, all positive | (1) | +x |
(Q) | Q1, Q2 positive Q3, Q4 negative | (2) | -x |
(R) | Q1, Q4 positive Q2, Q3 negative | (3) | +y |
(S) | Q1, Q3 positive Q2, Q4 negative | (4) | -y |
