JEE Main & Advanced Physics Simple Harmonic Motion Question Bank Time Period and Frequency

  • question_answer
    The equation of a simple harmonic motion is \[X=0.34\cos (3000t+0.74)\] where X and t are in mm and sec. The frequency of motion is                        [Kerala (Engg.) 2002]

    A)            3000                                         

    B)            \[3000/2\pi \]

    C)            \[0.74/2\pi \]                       

    D)            \[3000/\pi \]

    Correct Answer: B

    Solution :

               From given equation \[\omega =3000,\] Þ\[n=\frac{\omega }{2\pi }=\frac{3000}{2\pi }\]
