Vedclass · Answer

(A) An electric field is defined as the region around a charged particle or object within which a force would be exerted on other charged particles or objects.Mathematically,the electric field $E$ at a point is defined as the force $F$ experienced by a test charge $q_0$ placed at that point,divided by the magnitude of the test charge:$E = \frac{F}{q_0}$It is a vector quantity,and its $SI$ unit is $N/C$ (Newtons per Coulomb).
