Re: WBJEE Tutorial
As you want I am here giving you Tutorial /test paper for West Bangle Joint Entrance Examination (WBJEE). Test paper : 1. A whistle whose air column is open at both ends has a fundamental frequency of 5100 Hz. If the speed of sound in air is 340 ms–1, the length of the whistle, in cm, is (A) 5/3 (B) 10/3 (C) 5 (D) 20/3 Ans : (B) 4. In which of the following pairs, the two physical quantities have different dimensions? (A) Planck’s constant and angular momentum (B) Impulse and linear momentum (C) Moment of inertia and moment of a force (D) Energy and torque Ans : (C) To determine the coefficient of friction between a rough surface and a block, the surface is kept inclined at 45° and the block is released from rest. The block takes a time t in moving a distance d.The rough surface is then replaced by a smooth surface and the same experiment is repeated. The block now takes a time t/2 in moving down the same distance d. The coefficient of frict on is (A) 3/4 (B) 5/4 (C) 1/2 (D) 1/ 2 A drop of some liquid of volume 0.04 cm3 is placed on the surface of a glass slide. Then another glass slide is placed on it in such a way that the liquid forms a thin layer of area 20 cm2 between the surfaces of the two slides. To separate the slides a force of 16×105 dyne has to be applied normal to the surfaces. The surface tension of the liquid is (in dyne-cm–1) (A) 60 (B) 70 (C) 80 (D) 90 Ans : (C) In which of the following phenomena, the heat waves travel along straight lines with the speed of light ? (A) thermal conduction (B) forced convection (C) natural convection (D) thermal radiation Ans : (D) 15. An artificial satellite moves in a circular orbit around the earth. Total energy of the satellite is given by E. The potential energy of the satellite is (A) –2E (B) 2E (C) 2E/3 (D) –2E/3 Ans : (B) Hints : P.E. = 2(T.E.) 16. A particle moves with constant acceleration along a straight line starting from rest. The percentage increase in its displacement during the 4th second compared to that in the 3rd second is (A) 33% (B) 40% (C) 66% (D) 77% Ans : (B) Here is the attachment. WBJEE test paper |
