As you need Indian Institute of Space Science and Technology (IIST) ISAT entrance exam question paper, here I am giving: 1 The figure , on the right, shows a jar filled with two liquids of densities ρ and ρ/2 that do not mix. A cylinder made of a material of density 3ρ/4 is held in the jar at various depths starting from the position where the lower surface of the cylinder touches the upper surface AB of the liquid. Which of the following schematic curves best describes the buoyancy force F on the cylinder as a function of the displacement h from the starting position? 2. An infinitely large surface of uniform charge density has a disc of radius R cut out 3. All the five capacitors shown in the figure have the same capacitance C. The battery has emf V. The charge on the capacitor T is 4. The figure shows a wire mesh of infinite extent, such that the resistance between any two neighbouring vertices is equal. A steady current of 1A flows into the node P, from a current source, while a steady current of 1A is extracted from the node Q, as shown. Regard the situation as the superposition of two processes: the first in which the current flows into the mesh, and the second in which it flows out of the mesh. The steady current flowing in the segment PQ is equal to 5. In a Young’s double slit experiment, the separation between the slits is 1.0 mm and the distance between the slits and the screen is 1.0 m. The light falling on the slits contains mainly two wavelengths 600 nm and 500 nm. The least distance from the centre of the fringe pattern where the intensity corresponding to one of these wavelengths is zero, is (a) 0.30 mm (b) 0.75 mm (c ) 0.25 mm (d) 1.20 mm For detailed paper here is attachment:     |
