In forced oscillation of a particle the amplitude is maximum for a frequency $\omega _ { 1 }$ of the force, while the energy is maximum for a frequency $\omega _ { 2 }$ of the force, then\\
(1) $\omega _ { 1 } = \omega _ { 2 }$\\
(2) $\omega _ { 1 } > \omega _ { 2 }$\\
(3) $\omega _ { 1 } < \omega _ { 2 }$ when damping is small and $\omega _ { 1 } > \omega _ { 2 }$ when damping is large\\
(4) $\omega _ { 1 } < \omega _ { 2 }$ when damping is large
