NEET Physics Speed & Velocity Assertion Reason Question
Assertion (A): The stopping distance of a vehicle is proportional to the square of its initial velocity.
Reason (R): Instantaneous speed at an instant is equal to the magnitude of the instantaneous velocity at that instant.
Both A and R are true and R is the correct explanation of A.
Both A and R are true but R is not the correct explanation of A.
A is true but R is false.
A is false.
Correct Answer
Detailed Explanation
The assertion about stopping distance being proportional to the square of initial velocity is true. However, the reason provided relates to the definition of speed and velocity, not the explanation of the assertion.
