Answer
The correct answer is:
(f) both N/C and V/m
Work Step by Step
The force experienced by a charge $q$ in an electric field $E$ is $F = E~q$. Since $F$ is measured in units of $newtons$ and charge $q$ is measured in units of $coulombs$, the electric field $E$ must be measured in $N/C$
$N/C = (N~m)/(C~m) = J/(C~m) = V/m$
The correct answer is:
(f) both N/C and V/m
