For this figure, what is the magnitude of the electric field at point A? +5.0 nC 4.0 m A -10.0 nC 3.0 m

A simple and common technique for accelerating electrons is shown in the figure below, where a uniform electric field is created between two plates. Electrons are released, usually from a hot filament, near the negative plate, and there is a small hole in the positive plate that allows the electrons to continue moving. a) calculate the acceleration of the electron if the field strength is 4.20x104 N/C.

In the configuration shown in the picture below, what is the total pridicted electric field magnitude at point "a"

The figure shows an electric dipole. What is the magnitude of the dipole's electric field at point P? Assume that q = 9.14 x 10-6 C, d= 3.11 x 10 m, and r = 8.35 cm. L. Number i +q d/2 -9 d/2 Units
