Problem 18. Consider a point charge of charge q₁ = −3 × 10-6 C that is at the origin of coordinates in the x-y plane. A) Find the electric field at the point with coordinate xp = -1 m, yp=0. B) Find the voltage at the point with coordinate xp=-1 m, yp=0. Take the zero position for voltage to be infinitely far from the charge.
Problem 17. A) A proton moves through a voltage difference of AV = 100 V. Find the change in potential energy of the proton in eV and in J. B) An electron moves through a voltage difference of AV = 100 V. Find the change in potential energy of the electron in eV and in J.
