हिन्दीIf the displacement of a particle in SHM is given by \( x(t) = A\cos(\omega t + \phi) \), what is the expression for its instantaneous acceleration \( a(t) \)?
View Answer & Solution
Correct answer · Option B
\( -\omega^2 A \cos(\omega t + \phi) \)
Explanation
Differentiating displacement twice with respect to time gives \( a(t) = \frac{d^2 x}{dt^2} = -\omega^2 A\cos(\omega t + \phi) \).
