-1.602 x 10-19 Coulombs is the charge of what?
An electron
The charges that produce electric field lines have this unit for charge…
Coulombs
Increasing the magnitude of the charges while decreasing the distance between both charges will do what to the electrostatic force…
Greatly increase the electrostatic force
What occurs to the electric field lines and the electrostatic force the further away you go from a point charge

Picture this situation. Two positively charged plates are parallel with each other. An electron is then shot through the exact middle of these plates with a certain velocity. What will happen to the electron when it passes through this region?
The electron will continue moving past these plates even though it is attracted to the positive plates. The thing is, the electron is pulled toward each plate by the same amount and thus cancels each other out!
