Can an electron move from a point of higher potential to a point of lower potential? Can the value of electric potential be negative in an electric field? State Coulomb's law in words as well as in symbols. State the similarity and difference between Newton's gravitational law and Coulomb's law. (08-cq003)
No, an electron can not move from a point of higher potential to a point of lower potential. Yes. The value of electric potential can be negative in an electric field.
