The SI unit of electric field is

Question

Accepted Answer

B. {'text': 'newton per coulomb, equivalent to volt per metre', 'label': 'B'}

1. Electric field is defined as force per unit charge.
2. Base SI unit: newton per coulomb (N/C).
3. Alternative form: volt per metre (V/m), same magnitude.
4. Both are equivalent because 1 V/m = 1 N/C.
