Draw position-time graphs for two objects having zero relative velocity.

Explanation

Let is consider the two objects be at different position when `t=0` As the relatice velocity of the two objects is zero, wherfore the two objects must be moving with the same & unifrom velocity in the same direction. Since the slope of position-time graph of uniform notion in a st. line represents velocity, hecne the position-time graphs for two objects inmotion haveing relative velocity are parallel straight lines equally inclined to time axis as shown in Tig. 2 (a). 38.
