STANDARD Physics Acceleration Assertion Reason Question
Type: Assertion Reason-conceptual-Medium-Class 11
Assertion: A particle may be momentarily at rest and yet have non-zero acceleration. Reason: The zero velocity of a particle at any instant does not necessarily imply zero acceleration at that instant.
A
If both assertion and reason are true and reason is the correct explanation of assertion.
B
If both assertion and reason are true and reason is not the correct explanation off assertion.
C
It assertion is true but reason is false.
D
If both assertion and reason are false.
Correct Answer
Option A
Detailed Explanation
A particle can be momentarily at rest, such as at the top of its trajectory when thrown upwards, but still have non-zero acceleration due to gravity. The reason correctly explains that zero velocity does not imply zero acceleration.
