In the given graph betweentwo physical quantities 'a' and 'b' as shown in the figure 'b' is along x-axis while 'a' is along y-axis. The plot describes the motion of a particle in a straight line then

Answer»

Quantity 'B' may represent time.
Quantity 'a' can be velocity if motion is UNIFORM.
Quantity a should be displacement if motion in uniform
Quantity 'a' should be velocity if motion is uniformly accelerated.

Solution :Here if time .t. is represent along x-axis then the graph represent displacementtime graph for uniform motion INWHICH the displacement goes on increasing uniformly with time.
Also .a. can ACT as the acceleration for uniformly acceleratedmotion. Thus (a),(c),(d) can be taken to be correct (c) and (d) under different CONDITION as stated above.
