Question

For the graph given below choose the correct option :

$\begin{array}{cc}\text{Table A}& \text{Table B}\\ a)\text{Line A}& i)\text{Accelerated Motion}\\ b)\text{Line B}& ii)\text{Constant velocity (high magnitude)}\\ c)\text{Curve C}& iii)\text{At rest}\\ d)\text{Line E}& iv)\text{Constant Velocity (low magnitude)}\end{array}$

• A. a-i , b-iii , c-iv , d -ii
• B. a-iii , b-i , c-ii , d-iv
• C. a-iii , b-ii , c-i , d-iv
• D. a-iii , b-iv , c-i , d-ii

Answer 1

The correct option is D

a-iii , b-iv , c-i , d-ii

Slope of x-t graph is velocity.

In case of line A slope = 0 $\Rightarrow velocity=0$, that is the body is at rest.

Line B has a constant slope but the slope is less steeper than E though.
Therefore both line B and E represents that the body is moving with constant velocity, but magnitude of velocity of B is less than that of E.

In case of curve C slope is changing. This represents accelerated motion.
