Open in App
Solution
The correct option is A
When a velocity-time graph is parallel to the velocity axis, it means that velocity is increasing without any change in time.
Since, acceleration is the ratio of change in velocity to change in time, the acceleration will be infinite, which is not possible for any object. So, this graph is not a valid velocity-time graph of a particle.
