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.

Four charges Q1 ,
q2 ,
Q3 and Q4 of same magnitude are fixed along the x axis at x = −2a ,
then the SHM of the block will be : ,
v 0 . The block carries a charge +Q on its surface. lf now a uniform electrlc field E is switched-on as shown ,
A current I flows in a rectangularly shaped wire whose center lies at (x 0 ,0 , 0) and whose vertices are located at the point A(x 0 +d, −a, −b ),B (x 0 −d ,a ,−b), C(x 0 −d, a, +b), and D(x 0 +d,−a,+b) respectively. Assume that a, b, d <<x 0 . Find the magnitude of magnetic dipole moment vector of the rectangular wire frame in J/T. (Given: b = 10 m, I = 0.01 A, d = 4 m, a = 3 m.)
