Statement-1 : The position-time graph of a uniform motion in one dimension of a body can have negative slope.
Statement-2 : When the speed of body decreases with time, the position-time graph of the moving body has negative slope.

Options

A. If both assertion and reason are true and the reason is the correct explanation of the assertion.
B. If both assertion and reason are true but reason is not the correct explanation of the assertion.
C. If assertion is true but reason is false.
D. If the assertion and reason both are false.

Answer

C

Explanation

Negative slope of position time graph represents that the body is moving towards the negative direction and if the slope of the graph decreases with time then it represents the decrease in speed i.e. retardation motion. 8
