An electron of mass M kg and charge e coulomb travels from rest through a potential difference of V volts. The final energy in joules would be

Correct Answer

• **Formula:** Work Done = Charge × Potential Difference. • **Conversion:** Work done on the electron converts to Kinetic Energy. • **Result:** Energy ......

💡 Analysis & Explanation

• **Formula ▼

** Work Done = Charge × Potential Difference.

• **Conversion ▼

** Work done on the electron converts to Kinetic Energy.

• **Result ▼

** Energy (E) = $e \times V$ Joules (often denoted as electron-volts if unit is eV, but magnitude is eV).
