Question

The relative velocity vB A or vA B is zero for two particles moving along X-axis uniformly. The position-time graph for this situation will be (A) straight lines parallel but inclined to time axis (B) straight lines parallel and also parallel to time axis (C) straight lines intersecting each other at some point (D) curves and not straight lines

If vB A or vA B is zero, then vA=vB as vA B=vB A=|vA-vB| . For uniform motion, the position-time graph will be straight lines parallel to each other and inclined to time axis as shown below for given situation.

Q. The relative velocity $v_{B A}$ or $v_{A B}$ is zero for two particles moving along $X$ -axis uniformly. The position-time graph for this situation will be

straight lines parallel but inclined to time axis

straight lines parallel and also parallel to time axis

straight lines intersecting each other at some point

curves and not straight lines

If $v_{B A}$ or $v_{A B}$ is zero, then $v_{A} = v_{B}$ as
$v_{A B} = v_{B A} = ∣ v_{A} - v_{B} ∣$ .
For uniform motion, the position-time graph will be straight lines parallel to each other and inclined to time axis as shown below for given situation.
