Excerpt

red as above described, then the mechanical force between them is equal to QQ'/Kd^2 dynes. For constant charges and distances the mechanical force is inversely as the dielectric constant.

Electric Force.--If a small conducting body is charged with Q electrostatic units of electricity, and placed in any electric field at a point where the electric force has a value E, it will be subject to a mechanical force equal to QE dynes, tending to move it in the direction of the resultant electric force. This provides us with a definition of a unit of electric force, for it is the strength of an electric field at that point where a small conductor carrying a unit charge is acted upon by unit mechanical force, assuming the dielectric constant of the surrounding medium to be unity. To avoid unnecessary complications we shall assume this latter condition in all the following discussion, which is equivalent simply to assuming that all our electrical measurements are made in air or in vacuo.

Author of the Day

WJ Lundy
As a still-serving military veteran, WJ Lundy has over 15 years of combined service with the Army and Navy in Europe, the Balkans and Southwest Asia. He is also the author of the very successful WTF series, in which Lundy applies his military experience to paint action-packed, realistic scenes in a post-apocalyptic world where zombies roam the lands. Today, Lundy chats with us about his Escape omnibus, how he wrote his first novel in a notebook in Afghanistan and why his zombies are scarier than most.
