Assertion: A negative acceleration of a ...

Assertion: A negative acceleration of a body can be associated with a 'speeding up' of the body.
Reason: Increase in speed of a moving body is independent of its direction of motion.

A

If both assertion and reason are true and reason is the correct explanation of assertion.

B

If both assertion and reason are true but reason is not the correct explanation of assertion.

C

If assertion is true but reason is false.

D

If assersion is false but reason is true.

Text Solution

Verified by Experts

The correct Answer is:
B
A body having negative acceleration can be associated with a speeding up, if object moves along negative X-direction with increasing speed.
