Sample Paper for IIT JEE physics
I am searching here question paper for physics subject examination of IIT JEE in a PDF file format ? Here I am giving you question paper for physics subject examination of IIT JEE in a PDF file attached with it so you can get it easily. A spherical portion has been removed from a solid sphere having a charge distributed uniformly in its volume as shown in the figure. The electric field inside the emptied space is (A) zero everywhere (B) non-zero and uniform (C) non-uniform (D) zero only at its center A student performs an experiment to determine the Young’s modulus of a wire, exactly 2 m long, by Searle’s method. In a particular reading, the student measures the extension in the length of the wire to be 0.8 mm with an uncertainty of ±0.05 mm at a load of exactly 1.0 kg. The student also measures the diameter of the wire to be 0.4 mm with an uncertainty of ±0.01 mm. Take g = 9.8 m/s2 (exact). The Young’s modulus obtained from the reading is (A) (2 .0 ± 0.3) × 1011 N/m2 (B) (2 .0 ± 0.2) × 1011 N/m2 (C) (2 .0 ± 0.1) × 1011 N/m2 (D) (2 .0 ± 0.05) × 1011 N/m2 In the experiment to determine the speed of sound using a resonance column, (A) prongs of the tuning fork are kept in a vertical plane (B) prongs of the tuning fork are kept in a horizontal plane (C) in one of the two resonances observed, the length of the resonating air column is close to the wavelength of sound in air (D) in one of the two resonances observed, the length of the resonating air column is close to half of the wavelength of sound in air Water is filled up to a height h in a beaker of radius R as shown in the figure. The density of water is ρ, the surface tension of water is T and the atmospheric pressure is P0. Consider a vertical section ABCD of the water column through a diameter of the beaker. The force on water on one side of this section by water on the other side of this section has magnitude (A) 2 0 2P Rh R gh 2RT + π ρ − (B) 2 0 2P Rh R gh 2RT + ρ − (C) 2 2 0 P R R gh 2RT π + ρ − (D) 2 2 0 P R R gh 2RT A vertical iron rod has a coil of wire wound over it at the bottom end. An alternating current flows in the coil. The rod goes through a conducting ring as shown in the figure. The ring can float at a certain height above the coil.
