Velocity of Electron Solution

Follow our step by step solution on how to calculate Velocity of Electron?

FIRST Step Consider the formula

V v = \sqrt{\frac{2 \cdot [Charge-e] \cdot V}{[Mass-e]}}

Next Step Substitute values of Variables

∴

V v = \sqrt{\frac{2 \cdot [Charge-e] \cdot 0.715V}{[Mass-e]}}

Next Step Substitute values of Constants

∴

V v = \sqrt{\frac{2 \cdot 1.6E-19C \cdot 0.715V}{9.1E-31kg}}

Next Step Prepare to Evaluate

∴

V v = \sqrt{\frac{2 \cdot 1.6E-19 \cdot 0.715}{9.1E-31}}

Next Step Evaluate

∴

V v = 501508.986210137m/s

LAST Step Rounding Answer

∴

V v = 501508.9862m/s

How to Evaluate Velocity of Electron?

Velocity of Electron evaluator uses Velocity due to Voltage = sqrt((2*[Charge-e]*Voltage)/[Mass-e]) to evaluate the Velocity due to Voltage, The velocity of electron refers to its speed and direction of motion and it is determined by the conservation of energy principle. It essentially says that the change in kinetic energy of the electron is equal to the change in potential energy it experiences due to the electric field. Velocity due to Voltage is denoted by V_v symbol.
