Here I am giving you question paper for the IIT JAM Physics. Hope it helps you.

An X-ray diffraction (XRD) experiment is carried out on a crystalline solid having FCC structure at room temperature. The solid undergoes a phase transformation on cooling to
—20 °C and shows orthorhombic structure with small decrease in its unit cell lengths as compared to the FCC unit cell lengths. As a result, the (311) line of the XRD pattern corresponding to the FCC system
(A) will split into a doublet.
(B) will split into a triplet.
(C) will remain unchanged.
D) will split into two separate doublets.

(a) A solid having a simple cubic structure at room temperature with lattice parameter a and one valence electron per atom, is assumed to show free electron behaviour. Calculate the ma2nitude of the Fermi wave vector and the corresponding equivalent
temperature. (12)
(b) Find the ratio of the magnitude of the Fermi wave vector to the radius of the largest sphere that can be inscribed within the first Brillouin zone of the solid. (9)

Two electric dipoles P1 and P2 are placed at (0, 0, 0) and (1, 0, 0) respectively,
with both of them pointing in the +z direction. Without changing the orientations of the dipoles, P2 is moved to (0, 2, 0). The ratio of the electrostatic potential energy of the dipoles after moving to that before moving is


The ratio of the inner radii of two glass tubes of same length is 2. A fluid of viscosity flows through the first tube, and another fluid of viscosity
flows through the second one when equal pressure difference is applied across both of them. The ratio of the flow rate in the first tube to that in the second tube is
