NEET Physics (general) MCQ Question
Which of the following statements correctly describe the motion of a block attached to a spring on a frictionless surface?
The motion can be described using the equation f(t) = A cos ωt.
The block's motion is independent of its distance from the wall.
Increasing the argument of the function by an integral multiple of 2π results in the same position of the block.
The block experiences frictional forces that affect its oscillation.
Correct Answer
Detailed Explanation
The correct statement is A, as the motion of the block can indeed be described by f(t) = A cos ωt, indicating simple harmonic motion. Statement C is also true but does not address the function's description specifically. B and D are incorrect, as the motion is dependent on the distance from the wall and there are no frictional forces on a frictionless surface.
