Transcript. We can think of the forces between charges as something that comes from a property of space. That property is called the electric field. Charges shape the space around them, forming an electric field that interacts with other charges. The tutorial covers Coulomb''s Law, electric field lines, and the role of distance in field strength.
To find the electric field at a point due to a point charge, proceed as follows: Divide the magnitude of the charge by the square of the distance of the charge from the point. Multiply the value from step 1 with Coulomb''s constant, i.e., 8.9876 × 10⁹ N·m²/C². You will get the electric field at a point due to a single-point charge.
