Gravitational v Electrostatic Forces The similarities and differences between gravitational and electrostatic forces are listed in the table below: Table Comparing G and E Fields The ...
Electric Field of a Point Charge The electric field strength describes how strong or weak an electric field is at that point A point charge produces a radial field A charge sphere also acts ...
Motion of Charged Particles in an Electric Field A charged particle in an electric field will experience a force on it that will cause it to move If a charged particle remains still in a uni...
Uniform Electric Field Strength The magnitude of the electric field strength in a uniform field between two charged parallel plates is defined as: Where: E = electric field strength (V m-1) ...
Electric Field Strength Definition An electric field is a region of space in which an electric charge “feels” a force The electric field strength at a point is defined as: The electrostatic ...
Representing Electric Fields The direction of electric fields is represented by electric field lines Electric field lines are directed from positive to negative Therefore, the field lines mu...
Coulomb's Law All charged particles produce an electric field around it This field exerts a force on any other charged particle within range The electrostatic force between two charge...
Synchronous Orbits A synchronous orbit is: When an orbiting body has a time period equal to that of the body being orbited and in the same direction of rotation as that body These usually re...
Escape Velocity To escape a gravitational field, a mass must travel at the escape velocity This is dependent on the mass and radius of the object creating the gravitational field, such as a ...
