Task:

mb4_0021. The figure shows the lines of the electric field created by two oppositely charged plates.

A) Which lines (dashed or solid) are field lines of force? Explain the answer.

B) Select areas in the picture where the field, in your opinion, is uniform, non-uniform. Explain the answer.

C) Describe how the field strength varies when moving from the center of the pattern to

2. A charge of 4 nC was placed in a uniform electrostatic field. What is the field strength if the field acts on it with a force of 36 μN?

3. An electron with a speed of 4 * 109 cm/s flies into a flat capacitor, and its velocity vector burns in a plane parallel to the plates. Calculate the vertical displacement of an electron at the exit from the capacitor. The distance between the plates of the capacitor is 1 cm, the field strength is 30 000 N / C, condenser length 5 cm. The plates are horizontal.
