(a) What is the electric potential V at a distance r = 3.1 10-8 cm from a proton? (V)

(b) What is the electric potential energy in units J and eV of an electron at the given distance from the proton? (J) (eV)

Why are you asking these? These are standard formula, calculator work.

V=1/4PIeo * Q/r

electric potential energy=1/4PIeo *qQ/r
