Question

Assertion : In the s-t graph as shown in figure, velocity of particle is negative and acceleration is positive.

Reason : Slope of s-t graph is negative and increasing in magnitude.
A. If both Assertion and Reason are correct and Reason is the correct explanation of assertion.
B. If both Assertion and Reason are correct but Reason in not the correct explanation of Assertion.
C. If Assertion is true but Reason is false.
D. If Assertion is false but Reason is true.

Answer 1

Correct Answer - D
Slope is negative. Therefore velocity is negative. Slope (therefore velocity) is increasing in magnitude. Therefore acceleration is also negative.
