NEET Physics (general) MCQ Question
Which of the following statements about oscillations and simple harmonic motion is correct?
The displacement of a block attached to a spring is given by the function f(t) = A cos(ωt) where ω is the angular frequency.
An increase in the argument of the cosine function by an integral multiple of 2π does not affect the position of the block.
The motion of the block on a frictionless surface can be described in terms of acceleration and mean position.
The oscillation of the block is determined solely by its maximum displacement from the wall.
Correct Answer
Detailed Explanation
Statement A is correct as it directly references the function describing the block's motion. Statement B is misleading because it does not account for the periodic nature of the cosine function. Statement C is partially correct but does not fully capture the essence of simple harmonic motion. Statement D ignores the role of forces acting on the block.
