Question

Calculate the electron's speed after it has moved through a potential difference of 10 V.

Answer 1

To calculate the speed of an electron after moving through a 10 V potential difference, we can use the equation v = sqrt(2qV/m), where v is the speed, q is the charge on the electron, V is the potential difference, and m is the mass of the electron. Plugging in the values, we find the speed of the electron to be approximately
`5.51 X 10^6` m/s.

Step-by-step explanation:

To calculate the speed of an electron after it has moved through a potential difference of 10 V, we can use the equation:

v = sqrt(2qV/m)

where v is the speed of the electron, q is the charge on the electron
`(-1.60 X 10^-19` C), V is the potential difference (10 V), and m is the mass of the electron
`(9.11 X 10^-31`kg).

Plugging in the values, we have:

v = sqrt((2)(-
`1.60 X 10^-19`C)(10 V)/(
`9.11 X 10^-31`kg))

Solving for v, we find that the speed of the electron after moving through the 10 V potential difference is approximately
`5.51 X 10^6` m/s.
