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.)

A beam consisting of four types of ions A, B, C and D enters a region at P that contains a uniform magnetic field as shown in fig. The field is perpendicular to the plane of the paper, but its precise direction is not given. All ions in the beam travel with the same speed. The table on the next page shows the masses and charges of the ions

Three identical blocks each of mass m = 1 kg and volume 3 × 10^-4 m^3 are suspended by massless strings from a support as shown. Underneath are three identical containers containing the same amount of water that are placed over the scales. In Fig. (a), the block is completely out of the water, in Fig. (b), the block is completely submerged but not touching the beaker and in Fig. (c), the block rests on the bottom of the beaker. The scale in Fig (a) reads 14N.
