Vedclass · Answer

(C) The given equation is $x = P \sin \omega t + Q \sin \left(\omega t + \frac{\pi}{2}\right)$.Since $\sin \left(\omega t + \frac{\pi}{2}\right) = \cos \omega t$,the equation becomes $x = P \sin \omega t + Q \cos \omega t$.This represents the superposition of two simple harmonic motions with amplitudes $P$ and $Q$ that have a phase difference of $\frac{\pi}{2}$.The resultant amplitude $R$ is given by $R = \sqrt{P^2 + Q^2}$.The total energy $E$ of a particle performing $S$.$H$.$M$. is given by $E = \frac{1}{2} m \omega^2 R^2$.Substituting the value of $R^2 = P^2 + Q^2$,we get $E = \frac{1}{2} m \omega^2 (P^2 + Q^2)$.

$A$ body of mass '$m$' performs linear $S$.$H$.$M$. given by the equation $x = P \sin \omega t + Q \sin \left(\omega t + \frac{\pi}{2}\right)$. The total energy of the particle at any instant is

Two particles are executing simple harmonic motion of the same amplitude $A$ and frequency $\omega$ along the $x$-axis. Their mean positions are separated by a distance $X_0$ $(X_0 > A)$. If the maximum separation between them is $(X_0 + A)$,the phase difference between their motions is:

Three simple harmonic motions of equal amplitudes $A$ and equal time periods in the same direction combine. The phase of the second motion is $60^{\circ}$ ahead of the first and the phase of the third motion is $60^{\circ}$ ahead of the second. Find the amplitude of the resultant motion.

Two particles undergo $SHM$ along parallel lines with the same time period $(T)$ and equal amplitudes $(A)$. At a particular instant,one particle is at its extreme position while the other is at its mean position. They move in the same direction. They will cross each other after a further time:
