Zero Point Energy Solution

Follow our step by step solution on how to calculate Zero Point Energy?

FIRST Step Consider the formula

E 0 = (\frac{1}{2} \cdot ω') - (\frac{1}{4} \cdot x e \cdot ω')

Next Step Substitute values of Variables

∴

E 0 = (\frac{1}{2} \cdot 151/m) - (\frac{1}{4} \cdot 0.24 \cdot 151/m)

Next Step Convert Units

∴

E 0 = (\frac{1}{2} \cdot 15Diopter) - (\frac{1}{4} \cdot 0.24 \cdot 15Diopter)

Next Step Prepare to Evaluate

∴

E 0 = (\frac{1}{2} \cdot 15) - (\frac{1}{4} \cdot 0.24 \cdot 15)

LAST Step Evaluate

∴

E 0 = 6.6J
