Zero Point Energy of Particle in 2D Box Solution

Follow our step by step solution on how to calculate Zero Point Energy of Particle in 2D Box?

FIRST Step Consider the formula

Z.P.E = \frac{2 \cdot {[hP]}^{2}}{8 \cdot m \cdot {(l)}^{2}}

Next Step Substitute values of Variables

∴

Z.P.E = \frac{2 \cdot {[hP]}^{2}}{8 \cdot 9E-31kg \cdot {(1E-10A)}^{2}}

Next Step Substitute values of Constants

∴

Z.P.E = \frac{2 \cdot {6.6E-34}^{2}}{8 \cdot 9E-31kg \cdot {(1E-10A)}^{2}}

Next Step Convert Units

∴

Z.P.E = \frac{2 \cdot {6.6E-34}^{2}}{8 \cdot 9E-31kg \cdot {(1E-20m)}^{2}}

Next Step Prepare to Evaluate

∴

Z.P.E = \frac{2 \cdot {6.6E-34}^{2}}{8 \cdot 9E-31 \cdot {(1E-20)}^{2}}

Next Step Evaluate

∴

Z.P.E = 1219.5778937496J

Next Step Convert to Output's Unit

∴

Z.P.E = 7.61200318412691E+21eV

LAST Step Rounding Answer

∴

Z.P.E = 7.6E+21eV
