E = u / D uniform strength
KQ / R ~ 2 point charge
2 π K (electrostatic force constant) times the electric field intensity of an infinite flat plate with area density
That's enough. And UQ = kinetic energy change

How to deal with the formula symbols in high school physics elective (electric field and magnetic field)

Brother, this simple formula is a dead person is a living formula. You write it in a normal tree, and it is usually a positive sign. But you should be clear about the calculation process of the positive and negative signs. You don't need to write it on the answer sheet, and the numbers in the calculation process will be ok with the positive and negative signs

High school physics on the electric field, charged particles in the electric field and in the magnetic field movement. The most commonly used formula? And test hot

1、 . electric field: F = QE, e = u / D,
1. Accelerating linear motion: Qu = 1 / 2mV ^ 2
2. Quasi horizontal motion: vertical displacement y = 1 / 2at ^ 2, horizontal displacement L = v0t, where a = QE / M = Qu / MD, or add a gravity
It is also suitable for horizontal motion
2、 Magnetic field
F = QVB, radius r = MV / QB, period T = 2 π M / QB, movement time t = A / 2 π * t (a is deflection angle)
Hope to adopt! Not copy!
