NEET Energy in SHM MCQs & PYQs

Question 11:

moderate

A loaded vertical spring executes S.H.M. with a time period of 4 sec. The difference between the kinetic energy and potential energy of this system varies with a period of:

(1994)

In SHM, kinetic and potential energies (and their difference) oscillate with twice the frequency of the displacement. Therefore, their period is half of the displacement period, $ T' = T/2 = 4/2 = 2 $ sec.

Question 12:

easy

In case of a forced vibration, the resonance wave becomes very sharp when the:

(2003)

The sharpness of resonance in a forced oscillator is inversely proportional to the damping present in the system. Therefore, the resonance wave becomes very sharp when the damping force is small.
