Electric Field Strength
A gravity field is where a force is exerted on a mass; an electric field is a region
where a force is exerted on a charge.
The electric field strengthis defined as force per unit charge. In equation form
this is represented as:
E = F/Q
We can see that the graph shows a classic inverse square law.
Where two charged plates are close together, the radial fields of the charges
combine to make a uniform field .
Notice that the field bulges at the ends; generally we ignore this.
In this case we can show…
