how much energy is gain by an electron accelerated through a potential differenc of 30000v?
Energy=voltage*charge.
so what is the charge on one electron?
Bob's formula will give you the correct answer in Joules.
If you used energy units of electron Volts (eV), as is often done in physics, the answer would be just 30,000
To calculate the energy gained by an electron accelerated through a potential difference of 30000 V, you can use the equation:
Energy gained (Joules) = charge of the electron (Coulombs) × potential difference (Volts)
The charge of an electron is approximately 1.6 × 10^-19 Coulombs.
Plugging in the values, we have:
Energy gained = (1.6 × 10^-19 C) × 30000 V
Calculating the result:
Energy gained = 4.8 × 10^-15 Joules
Therefore, the electron gains approximately 4.8 × 10^-15 Joules of energy.
To calculate the energy gained by an electron accelerated through a potential difference of 30,000V, you can use the formula:
Energy = q × V
Where:
Energy is the energy gained,
q is the charge of the electron (1.6 × 10^-19 coulombs),
V is the potential difference (30,000V).
Substituting the values into the formula:
Energy = (1.6 × 10^-19 C) × (30,000V)
Now, let's calculate the energy by multiplying the charge of the electron by the potential difference:
Energy = 4.8 × 10^-14 J
Therefore, the energy gained by an electron accelerated through a potential difference of 30,000V is approximately 4.8 × 10^-14 Joules.
