Total Energy of Particle in 2D Box Solution

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

FIRST Step Consider the formula

E = ({(n x)}^{2} \cdot \frac{{([hP])}^{2}}{8 \cdot m \cdot {(l x)}^{2}}) + ({(n y)}^{2} \cdot \frac{{([hP])}^{2}}{8 \cdot m \cdot {(l y)}^{2}})

Next Step Substitute values of Variables

∴

E = ({(2)}^{2} \cdot \frac{{([hP])}^{2}}{8 \cdot 9E-31kg \cdot {(1.01A)}^{2}}) + ({(2)}^{2} \cdot \frac{{([hP])}^{2}}{8 \cdot 9E-31kg \cdot {(1.01A)}^{2}})

Next Step Substitute values of Constants

∴

E = ({(2)}^{2} \cdot \frac{{(6.6E-34)}^{2}}{8 \cdot 9E-31kg \cdot {(1.01A)}^{2}}) + ({(2)}^{2} \cdot \frac{{(6.6E-34)}^{2}}{8 \cdot 9E-31kg \cdot {(1.01A)}^{2}})

Next Step Convert Units

∴

E = ({(2)}^{2} \cdot \frac{{(6.6E-34)}^{2}}{8 \cdot 9E-31kg \cdot {(1E-10m)}^{2}}) + ({(2)}^{2} \cdot \frac{{(6.6E-34)}^{2}}{8 \cdot 9E-31kg \cdot {(1E-10m)}^{2}})

Next Step Prepare to Evaluate

∴

E = ({(2)}^{2} \cdot \frac{{(6.6E-34)}^{2}}{8 \cdot 9E-31 \cdot {(1E-10)}^{2}}) + ({(2)}^{2} \cdot \frac{{(6.6E-34)}^{2}}{8 \cdot 9E-31 \cdot {(1E-10)}^{2}})

Next Step Evaluate

∴

E = 4.78218956474698E-17J

Next Step Convert to Output's Unit

∴

E = 298.4806659789eV

LAST Step Rounding Answer

∴

E = 298.4807eV
