Question

Define electric field at a point..​

Answer 1

Answer:The electric field, E, at a given point is defined as the (vector) force, F, that would be exerted on a stationary test particle of unit charge by electromagnetic forces (i.e. the Lorentz force). A particle of charge q would be subject to a force F=qE.

Answer 2

Answer: Electric field is defined as the electric force per unit charge. The direction of the field is taken to be the direction of the force it would exert on a positive test charge. The electric field is radially outward from a positive charge and radially in toward a negative point charge.
