The variation of quantity A with quantity B, plotted in Fig. 3.2 describes the motion of a particle in a straight line.
(a) Quantity B may represent time.
(b) Quantity A is velocity if motion is uniform.
(c) Quantity A is displacement if motion is uniform.
(d) Quantity A is velocity if motion is uniformly accelerated.
The correct answer is the option:
(a) Quantity B may represent time.
(c) Quantity A is displacement if the motion is uniform.
(d) Quantity A is velocity if the motion is uniformly accelerated.
Explanation:
Verification of opt (a) & (d)
If the quantity B would have represented velocity instead of time, then the graph would’ve become a straight line, viz., uniformly accelerated motion, hence the motion is not uniform.
Verification of opt (c)
If A represents displacement and B represents time, then the graph will be a straight line which would represent uniform motion.
