Kinematics Question 83
Assertion : The position-time graph of a uniform motion in one dimension of a body can have negative slope. Reason : When the velocity of body is negative, 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 are both false.
