Point masses m₁ and m₂ are placed at the opposite ends of a rigid rod of length L and negligible mass. The rod is to be set rotating about an axis perpendicular to it. The position of point P on this rod through which the axis should pass, so that the work required to set the rod rotating with angular velocity ω₀ is minimum, is given by m 1 m 2 P (L – x) x ₀

A proton and an alpha particle both enter a region of uniform magnetic field B, moving at right angles to the field B. If the radius of circular orbits for both the particles is equal and the kinetic energy acquired by proton is 1 MeV, the energy acquired by the alpha particle will be

A plank with a box on it at one end is gradually raised about the other end. As the angle of inclination with the horizontal reaches 30°, the box starts to slip and slides 4.0 m down the plank in 4.0 s. The coefficients of static and kinetic friction between the box and the plank will be, respectively mg θ

NEET (UG) 2015 (Phase II) is part of our PRO plan. The latest year's NEET paper is always free; older papers are available with an AajExam PRO subscription that unlocks the full NEET PYQ archive.
The paper contains 180 multiple-choice questions to be attempted in 180 minutes for a total of 720 marks, with 1 negative marking per wrong answer.
The NEET 2015 paper covers the following sections: Physics, Chemistry, Biology. Each section is designed to test a specific skill set required for the NEET exam.
Yes. Every question on this PYQ paper has the correct answer and a detailed explanation. After submitting the test, you can review each question with step-by-step solutions, concept references, and tips on how to solve similar questions faster.
Yes. You can attempt this PYQ paper as many times as you like. Each attempt is recorded separately so you can track improvement in score, accuracy, and time-management.
Government exam toppers consistently say PYQ practice is the single highest-leverage strategy. NEET repeats question patterns, frequently-tested concepts and difficulty distribution year after year. Solving 8-10 PYQ shifts before the exam dramatically improves time management and confidence.
