1 V/m= _______


1 V/m= _______
A. 1N/C
B. 3*10^10 N/C
C. 10^7 N/C
D. 10^10 N/C
The correct option is A. 1N/C

From the definition, we know that electric field E=\(\frac {-dv}{dx}\). Therefore V/m is the unit of electric field intensity. 1 V/m means the amount of electric field in which if we move a unit positive charge by 1 m, the work done will be 1N. Therefore, the electric field will be 1N/C.
