    F(Newtons) = kQ*Q / r^2 ........coulombs law

    => N/C=F(newtons)/Q = kQ / r^2 .......1

    F/Q= E(Electric field) = kQ / r^2

    =>V(Electric potential) = E*r ............2

    From 1 and 2

    F/Q = V/r = (volt /meter) = (newtons/coulombs)

    Hence proved (volt per meter) is equivalent to (newtons per coulomb)

    1 volt = joule/coulomb

    1 Joule = N*m

    V/m =J/m*C = N*m/m*C = N/C
