What is the definition of electric potential? The problem tells you how much the electron's electric potential will change. How much will its potential energy change? How much will its kinetic energy change? Assume the electron starts at test. How much velocity does it acquire?hotstuff said:Electrons in a television set are accelerated through a potential difference of 2.0 kV.
(a) Find the speed of the electrons when they reach the screen. Ignore any relativistic effects.
how to do this i have no idea what formula to use

The formula for calculating electron speed is: v = √(2eV/m), where v is the electron speed in meters per second, e is the charge of an electron (1.602 x 10^-19 Coulombs), V is the potential difference in volts, and m is the mass of an electron (9.11 x 10^-31 kilograms).
The 2.0 kV potential difference is the amount of electric potential energy that is applied to the electrons in the TV screen. This potential difference determines the speed at which the electrons will travel in the screen, and ultimately affects the brightness and clarity of the images on the screen.
The unit of measurement for electron speed in this calculation is meters per second (m/s).
Yes, there are other factors that can affect the electron speed in a TV screen, such as the distance between the cathode and anode, the strength of the electric field, and the temperature of the electrons.
Calculating electron speed helps in understanding the functioning of a TV screen by providing insights into the behavior of electrons within the screen. This information can be used to optimize the design and performance of TV screens, and to troubleshoot any issues that may arise. Additionally, understanding electron speed can also aid in the development of new technologies and advancements in the field of electronics.
