| Direction: For questions 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 If the net external force on the body is zero, then its acceleration is zero. |
| Reason Acceleration does not depend on force. |
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: C
Solution :
| A is true but R is false. |
| \[\because \operatorname{Acceleration} =\frac{Force}{Massa}\] |
| Acceleration \[\propto \] Force (\[\because \] Mass = constant) |
| i.e. If net external force on the body is zero, |
| then acceleration will be zero. |
