Field line near the electrodes for the different electrode

[xswtxoj]

1. Can someone explain the density of the field line near the electrodes for the different electrode.
2. How would the different field densities described above affect the force on a charge?

is an example of the field lines, which were once considered lines of force (faraday). charges will accelerate faster in denser fields, which exist very close to the electrodes. everything is summing fields, and the fields in question are 1/r^2 for the force.
