NEET Physics (general) Assertion Reason Question
Type: Assertion Reason-assertion-Hard-Class 11
Assertion (A): The displacement of a block attached to a spring can be described as a cosine function of time. | Reason (R): The block's motion is periodic and repeats every 2π radians.
A
Both A and R are true and R is the correct explanation of A.
B
Both A and R are true but R is not the correct explanation of A.
C
A is true but R is false.
D
A is false.
Correct Answer
Option A
Detailed Explanation
According to the NCERT context, the displacement of a block in simple harmonic motion is described by a cosine function, and the periodic nature is captured by the argument increasing by 2π radians, confirming both A and R.
