By observing the given graph, one can say that between 4 and 6 seconds. The object is not moving, therefore the correct answer is the option B
What is Velocity?
The total displacement covered by any object per unit of time is known as velocity. It depends on the magnitude as well as the direction of the moving object.
As given in the problem position-time graph of an object.
As we know that slope of the position time curve represents the velocity of the object
By looking at the curve between 4 and 6 seconds the slope of the line is zero this means the velocity of the object is zero between the 4 and 6 seconds, this means the object is not moving and it is at rest.
Thus, By observing the given graph, one can say that between 4 and 6 seconds. The object is not moving, therefore the correct answer is the option B
