NEET Physics (general) MCQ Question
Which combination of statements about motion in a plane is correct?
A: The resultant vector can be obtained using the triangle law. B: Acceleration can be defined as the limit of average acceleration as time approaches zero. C: The magnitude of acceleration is always constant.
A: The resultant vector can be obtained using the triangle law. B: Acceleration can be defined as the limit of average acceleration as time approaches zero. C: The direction of acceleration is always the same as the direction of velocity.
A: The resultant vector can be obtained using the triangle law. B: Acceleration can be defined as the limit of average acceleration as time approaches zero. C: The magnitude of acceleration can vary.
A: The resultant vector can be obtained using the triangle law. B: Acceleration can be defined as the limit of average acceleration as time approaches zero. C: The resultant vector direction is independent of the method used to obtain it.
Correct Answer
Detailed Explanation
Statements A and B are correct as per the methods of vector addition and the definition of instantaneous acceleration. However, statement C is also correct as the magnitude of acceleration can vary, especially in non-uniform motion, which is not stated as a constant.
