DC Voltage Solution

Follow our step by step solution on how to calculate DC Voltage?

FIRST Step Consider the formula

V = \frac{0.5 \cdot [Mass-e] \cdot {E vo}^{2}}{[Charge-e]}

Next Step Substitute values of Variables

∴

V = \frac{0.5 \cdot [Mass-e] \cdot {6.2E+7m/s}^{2}}{[Charge-e]}

Next Step Substitute values of Constants

∴

V = \frac{0.5 \cdot 9.1E-31kg \cdot {6.2E+7m/s}^{2}}{1.6E-19C}

Next Step Prepare to Evaluate

∴

V = \frac{0.5 \cdot 9.1E-31 \cdot {6.2E+7}^{2}}{1.6E-19}

Next Step Evaluate

∴

V = 10927.7809847955V

Next Step Convert to Output's Unit

∴

V = 10.9277809847955kV

LAST Step Rounding Answer

∴

V = 10.9278kV
