Question

Figure shows the displacement (x) - time (t) graph of a particle moving on the x-axis. Then

1) the particle is at rest 

2) the velocity of particle increases upto time t₀ and then increases 

3) the velocity of particle increases upto time t₀ and then becomes constant. 

4) the particle moves at a constant velocity upto a time t₀, and then stops.

Answer 1

Correct option is 4) the particle moves at a constant velocity upto a time t₀, and then stops.

The particle moves at a constant velocity up to a time t₀ and then stops.

The slope of the x-t graph gives the velocity. In the graph, the slope is constant from t = 0 to t = t₀, so the velocity is constant. After t = t₀, the displacement is zero; i.e, the particle stops.
