Uniform Electrostatic Field
This page delves into the motion of charged particles in a uniform electrostatic field, which is fundamental for understanding Mouvement dans un champ électrique uniforme Motioninauniformelectricfield.
The setup consists of two parallel plates creating a uniform electric field E. A charged particle q with mass m is introduced into this field with an initial velocity v₀ at an angle α.
Definition: A uniform electric field is a region where the electric field strength and direction are constant at all points.
Using Newton's Second Law in a Galilean reference frame, the equations of motion are derived. The acceleration, velocity, and position equations are presented for both x and y components.
Highlight: The electric force on the particle is given by F = qE, which results in a constant acceleration a = qE/m in the direction of the field.
Example: For a positively charged particle in a downward-pointing electric field, the vertical acceleration is ay = -qE/m, leading to a parabolic trajectory similar to projectile motion in a gravitational field.
