A small object has a charge of q = 4e, where e is the charge on an electron. (A) Determine the electric potential (in V) due to the charge at a distance r = 0.290 cm from the charge. (B) Determine the electric potential difference (in V) between a point that is 4r away and this point, that is V(4r) − V(r). (C) Determine the electric potential difference (in V) between a point that is (r/4) away and this point, that is V(r/4)-V(r). (D) How would the answers change if the electrons are replaced by protons?
