JEE Main 18 March 2021, Shift 2, Physics Q8

Question 8 of 90 in this shift, Physics question 8 of 30, Section A.

The velocity - displacement graph of a particle is shown in the figure. The acceleration - displacement graph of the same particle is represented by :

The figure, in words

Stem figure: v (vertical) vs x (horizontal) graph with origin O; a straight line falls from vov_o on the v axis to xox_o on the x axis. Options are a vs x graphs with origin O.
  1. (1)[figure: a vs x graph; a horizontal straight line below the x axis (negative constant a)]
  2. (2)[figure: a vs x graph; straight line starting at a positive value on the a axis and decreasing to zero at a point on the x axis]
  3. (3)[figure: a vs x graph; straight line starting at a negative value on the a axis and rising to zero at a point on the x axis]Official answer
  4. (4)[figure: a vs x graph; a horizontal straight line above the x axis (positive constant a)]

Question text from the official JEE Main paper published by NTA; answer from the final answer key. Chapter, topic and idea tags, difficulty and skill are Lumi’s. This question needs a figure we do not reproduce; it is described in words above. Lumi analyses 108 of the 174 JEE Main shifts held from 2017 to 2026.
