NEET 2014 Physics Simple Harmonic Motion MCQ Question
Type: MCQ-conceptual-Medium-Class 11
The oscillation of a body on a smooth horizontal surface is represented by the equation, X = Acos(ωt) where, X = displacement at time t, ω = frequency of oscillation. Which one of the following graphs shows correctly the variation a with t? Here a = acceleration at time t, T = time period
A
B
C
D
Correct Answer
Option A
Detailed Explanation
The acceleration is the second derivative of displacement with respect to time, which is proportional to -cos(ωt), matching the graph in option A.
