Question

Compare the velocity of the two particles $A$ and $B$ as per the displacement-time curve shown below.

• A. Velocity of particle $A$ is less than velocity of particle $B$
• B. Velocity of particle $B$ is less than velocity of particle $A$
• C. Velocity of particle $A$ is equal to velocity of particle $B$
• D. Can't say.

Answer 1

The correct option is B Velocity of particle $B$ is less than velocity of particle $A$

Given Displacement-Time curve as

As we know that the velocity of the particle is given by the slope of the Displacement-Time curve.
Here, it is clear that the slope of particle $A$ is more compared to particle $B$ since, $A$ is having approximately same displacement compared to $B$ but has taken less time than $B$.
Hence, $v_A>v_B$
