| Direction: For question given below two statements are given-one labelled Assertion (A) and the other labelled Reason (R). Select the correct answer to these questions from the codes [a], [b], [c] and [d] as given below |
| Assertion The position-time graph of a uniform motion in one-dimension of a body can have negative slope. |
| Reason When the speed of body decreases with time, the position-time graph of the moving body has negative slope. |
A) Both A and R are true and R is correct explanation of the A.
B) Both A and R are true but R is not the correct explanation of the A.
C) A is true but R is false.
D) A is false but R is true.
Correct Answer: A
Solution :
Negative slope of position-time graph represents that the body is moving towards the negative direction and if the slope decreases with time, then it represents the decrease in speed or retardation in motion.
