Electric Potential and Potential Energy
Due to Point Charges (12)
(a) Calculate the electric potential $$0.250 \,cm$$ from an
electron.
(b) What is the electric potential difference
between two points that are $$0.250 \,cm$$ and $$0.750 \,cm$$ from an electron?
(c) How would the answers change if
the electron were replaced with a proton?
