1.	Assertion : The position-time graph of a body moving uniformly is a straight line parallel to position-axis. Reason : The slope of position-time graph in a uniform motion gives the velocity of an object.A. If both assertion and reason are trure and reason is the correct explanation of assertion.B. If both assertion and reason are true but reason is not the correct explanations of assertion.C. If assertion is true but reason is false.D. If both assertion and reason is false
Answer» Correct Answer - (d) If the position-time graph of a body moving uniformly in a straight line is parallel to position axis, it means that the position of body is changing at constant time, which is absurd and shows that the velocity of the body is infinite.
