JEE Advanced 2017 Physics Solved Question Paper-1
Find the detailed solution of Physics section of JEE Advanced 2017 Paper-1. With the help of this solved paper students can understand the pattern and difficulty level of the questions asked in JEE Advanced 2017 and be prepared accordingly for the coming JEE Advanced 2018.
In this article, you will get complete detailed solutions of IIT JEE Advanced 2017 Physics Paper-1. This paper will be helpful for those students who are going to appear for the exam next year. Previous year papers help the students to understand the pattern of the examination. Generally questions in JEE Main/Advanced are not repeated but the concept on which questions are being asked keeps on repeating year after year. The students must go through the complete paper in order to understand the examination pattern and the level of questions asked in the examination.
There were three parts in the question paper – Physics, Chemistry and Mathematics. Each part has 18 questions, distributed over three sections. So, in total the question paper consists of 54 questions.
There are three sections in the paper as below:
Section I consists of multiple correct answers type questions.
Section II consists of Integer type questions and
Section III consists of matching type questions.
Few fully solved sample questions from the Question Paper are given below:
Q. A circular insulated copper wire loop is twisted to form two loops of area A and 2A as Shown in the figure. At the point of crossing the wires remain electrically insulated from each other. The entire loop lies in the plane (of the paper). A uniform magnetic field points into the plane of the paper. At t = 0, the loop starts rotating about the common diameter as axis with a constant angular velocity in the magnetic field. Which of the following options is/are correct?
[A] The emf induced in the loop is proportional to the sum of the areas of the two loops,
[B] The rate of change of the flux is maximum when the plane of the loops is perpendicular to plane of the paper
[C] The net emf induced due to both the loops is proportional to cosωt
[D] The amplitude of the maximum net emf induced due to both the loops is equal to the amplitude of maximum emf induced in the smaller loop alone
Q. A flat plate is moving normal to its plane through a gas under the action of a constant force F. The gas is kept at a very low pressure. The speed of the plate v is much less than the average speed u of the gas molecules. Which of the following options is/are true?
[A] At a later time the external force F balances the resistive force
[B] The plate will continue to move with constant non-zero acceleration, at all times
[C] The resistive force experienced by the plate is proportional to v
[D] The pressure difference between the leading and trailing faces of the plate is proportional to uv
Q. A block of mass M has a circular cut with a frictionless surface as shown. The block rests on the horizontal frictionless surface of a fixed table. Initially the right edge of the block is at x = 0, in a co-ordinate system fixed to the table. A point mass in is released from rest at the topmost point of the path as shown and it slides down. When the mass loses contact with the block, its position is x and the velocity is v. At that instant, which of the following options is/are correct?
