Weightage: what the paper actually did

Laws of Motion carried 3 questions in the NEET 2026 paper. One paper is a data point, not a destiny: NTA moves weight between chapters every cycle, which is why the weightage tables deserve care. The stable facts are the paper's shape: 180 questions, 720 marks, +4 right, −1 wrong.

Question 1 · NEET 2026

A car travels on a circular racetrack of radius 50 m, which is banked at an angle θ\theta. If the car travels at a speed 10 ms−1\text{ms}^{-1}, then the wear and tear on its tyres is minimum. Taking the acceleration due to gravity to be 10 ms−2\text{ms}^{-2}, the value of θ\theta is:
  1. A.tan⁡−1(15)\tan^{-1}\left(\frac{1}{5}\right)
  2. B.tan⁡−1(25)\tan^{-1}\left(\frac{2}{5}\right)
  3. C.tan⁡−1(3/2)\tan^{-1}(\sqrt{3}/2)
  4. D.tan⁡−1(23)\tan^{-1}(2\sqrt{3})
Answer and explanation

Answer: A

Minimum wear and tear is the exam's way of saying no sideways friction is needed, i.e. the car is at the optimum (design) speed of the banked track. Then the horizontal component of the normal reaction alone supplies the centripetal force, giving tan⁡θ=v2rg=10250×10=15\tan\theta = \frac{v^2}{rg} = \frac{10^2}{50 \times 10} = \frac{1}{5}, so θ=tan⁡−1(1/5)\theta = \tan^{-1}(1/5).

How to practise Laws of Motion

Chapter by chapter, against real past-paper questions, on a screen: NEET is computer based from 2027. Read the chapter once, then attempt its PYQs until your accuracy stops climbing, and let the wrong answers tell you which lines to reread. If the chapter keeps refusing to stick, that has its own guide. There is also a free NEET mini mock with answers.

Is Laws of Motion important for NEET 2027?

It is part of the Physics syllabus the paper draws from, and NEET 2027 is computer based, so practise it on a screen. Your own accuracy in the chapter matters more than any weightage table: a heavy chapter you already score well on needs less time than a light one you keep missing.
