What is the relationship between the electric field strength and the charge of the point source?

The strength of an electric field as created by source charge Q is inversely related to square of the distance from the source. This is known as an inverse square law. Electric field strength is location dependent, and its magnitude decreases as the distance from a location to the source increases.

Beside this, how is charge density related to electric field?

Relation of Electric Field to Charge DensitySince electric charge is the source of electric field, the electric field at any point in space can be mathematically related to the charges present. The divergence of the electric field at a point in space is equal to the charge density divided by the permittivity of space.

Also, why is the electric field independent of the distance from the plane? Hence, the electric field at a point due to a uniformly charged infinite plane sheet is independent of the distance from it. (i) If the sheet is positively charged, field is directed away from the sheet of charge. (ii) If the sheet is negatively charged, field is directed towards the sheet of charge.

Hereof, what is the relationship between field and electric force?

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.

What is the significance of electric field?

The electric field at any point in space around a system of charges represents the force a unit positive test charge would experience if placed at that point. The term field in physics generally refers to a quantity that is defined at every point in space and may vary from point to point.
