www Electric field between 250 m high and 200 m thick cloud and the surface of earth is 150 v/m directed vertically. At the top of the cloud is +q and the bottom of cloud is -q making the cloud neutral. Calculate the magnitude of the external electrical force on the cloud.
3. The electric field is created by infinite parallel plates carrying a charge uniformly distributed over the area with surface densities δ1 = 10 nC / m ^ 2, b2 = 3 nC / m ^ 2. The distance between the plates is d = 6 mm. Determine: a) the strength of the electric field outside and between the plates; b) the potential difference between the plates; c) the density of the surface charge and the density of the induced charge on both sides of each plate. Build graphs of changes in E and f along a line perpendicular to the plates. How will the graphs change if the distance between the plates is doubled?

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 3.45 x 104 N/C. m/s² (b) Why will the electron not be pulled back to the positive plate once it moves through the hole? O The force of gravity is too strong. O There is no field outside the plates. O The other side of the positive plate also has a negative charge.
