Re: IIT Papers PDF
You want previous IIT JEE question paper so I have it in pdf file. Following are questions in paper: 1. In the determination of Young’s modulus 2 Y d = p l by using Searle’s method, a wire of length L = 2m and diameter d = 0.5 mm is used. For a load M = 2.5 kg, an extension l = 0.25 mm in the length of the wire is observed. Quantities d and l are measured using a screw gauge and a micrometer, respectively. They have the same pitch of 0.5 mm. The number of divisions on their circular scale is 100. The contributions to the maximum probable error of the Y measurement (A) due to the errors in the measurements of d and l are the same. (B) due to the error in the measurement of d is twice that due to the error in the measurement of l. (C) due to the error in the measurement of l is twice that due to the error in the measurement of d. (D) due to the error in the measurement of d is four times that due to the error in the measurement of l. 2. A small mass m is attached to a massless string whose other end is fixed at P as shown in the figure. The mass is undergoing circular motion in the x-y plane with centre at O and constant angular speed w. If the angular momentum of the system, calculated about O and P are denoted by O Lr and P L r respectively, then z P O m w (A) O L r and P L r do not vary with time. (B) O L r varies with time while P L r remains constant. (C) O L r remains constant while P L r varies with time. (D) L r and L r both vary with time. Complete questions are given in attached pdf file. You are free to download it. |
