| 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 Acceleration and displacement are in the opposite directions during retardation. |
| Reason Acceleration is given as the change in velocity per unit time. |
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 :
Acceleration is defined as the rate of change of velocity with respect to time and negative acceleration is called retardation. Displacement is length of the shortest pat measured in direction from initial position to final position of the object.
