STANDARD Physics Simple Harmonic Motion MCQ Question
Type: MCQ-conceptual-Medium-Class 11
For a particle executing simple harmonic motion the displacement x is given by x = A cos ωt. Identify the graph, which represents the variation of potential energy (U) as a function of time t and displacement x.
A
I, III
B
II, III
C
I, IV
D
II, IV
Correct Answer
Option D
Detailed Explanation
Given x = A cos ωt, the potential energy U = 1/2 mω²x² = 1/2 mω²A² cos² ωt. The graph between potential energy U and time t is curve II, and between U and x is curve IV.
