2. Suppose we have an infinitely long wire with uniform line charge density λ = -1.00 × 10⁹ C/m lying flat on the ground. The wire is fully stretch out (not coiled up). a) How strong is the repulsive electric force on an electron placed 1.00 m above the wire? Hint: this is another Gauss' Law problem, just with some extra calculations after. b) How does this compare the gravitational force on the electron pulling it down?

Problem 12: A simple and common technique for accelerating electrons is shown in the figure, which depicts a uniform electric field 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 pass through.
