Graphs are very useful to represent a physical situation. Various quantities can be easily represented on graphs and other quantites can be determined from the graph. For example the slope of velocity-time graph represents instantaneous acceleration. For a motion with constant acceleration slope of velocity-time graph is constant. If acceleration is changing with time, slope with change and thus velocity-time graph will be a non-linear curve. Further the area of velocity-time graph gives displacement.
The velocity-time graph for two objects P and Q are shown. The ratio of their respective acceleration is

A

1

B

`sqrt3`

C

`(1)/(sqrt3)`

D

None of these
