Question #93cfe

Answer 1

`~~27xx10^"-21"J`

Explanation:

If a particle of mass m acts as harmonic osciillator of angular frequency w under a periodic force having force constant k then we have the relation.

`w=sqrt(k/m)`

Again the zero point energy of the oscillator is

`E_0=1/2*h*w," h= Planck's constant"`

`E_0=1/2*6.626*10^"-34"*sqrt(155/(2.33xx10^"-26")J`

`=3.313*10^"-21"*sqrt(155/2.33)J`
`~~27xx10^"-21"J`
