At what displacement (i) the PE and (ii) KE of a simple harmonic oscillator is maximum?

Text Solution

Verified by Experts

(i) PE of a simple harmonic oscillator is maximum at
`x=pmA`.
PE at that instant, `U=1/2momega^(2)A^(2)`
(ii) KE of a simple harmonic oscillator is maximum at the position of equilibrium, x = 0.
KE at that instant, `K=1/2momega^(2)A^(2)`

The displacement equation of a simple harmonic motion is x=Asin(omegat+phi) . Show that the relation between velocity v and acceleration a of the motion is omega^(2)v^(2)+a^(2)=omega^(4)A^(2) .

An electric dipole had been formed by placing two particles each of mass m at the two ends of a light rod of length l. The charges of the two particles are +q and -q . This dipole is placed in a uniform electric field E in such a way that its axis is parallel to the direction of the field. The dipole is now deflected through a small angle. Show that for small angular displacement, the dipole will execute angular simple harmonic motion. Calculate the time period of the simple harmonic motion.
