Electric fields are a way to think about how particles interact with each other, and are thought of propagating out from protons and into electrons. With this topic, youll not only learn the physics of electric fields, but also applicable modelling techniques. The electric field that one point in space ‘feels due to one or more particles utilizes the property of superposition in that the sum of the electric field(s) produced by each particle in a relative frame of reference is the total electric field felt at that point. When dealing with charged objects, you can use their charge density to find their total charge. The key to solving any vector-related charged object problem is to break up the object into small pieces and integrate, draw a diagram of the problem, and use superposition to simplify your math.
The magnitude of the electric force (F) exerted on an object with charge q by an electric field E is F=qE.
The magnitude of the electric field vector is proportional to the net electric charge of the object(s) creating the field.
The electric field outside a spherically symmetric charged object is radial and follows an inverse square law as a function of the distance from the center of the object.
The electric field around dipoles and other systems of electrically charged objects is radial and follows an inverse square law as a function of the distance from the center of the object.
The electric field inside a conductor at equilibrium is zero.
