Physics- E-fields

Define Coloumbs Law

the magnitude of force between two point charges in a vacuum is directly proportional to the product of their charges and is inversely proportional to the square of the distance between the charges.

Define Electric field strength

the force per unit charge experienced by an object in an electric field

In E=V/d what is V

Potential difference

Define Electric potential

potential energy per unit charge of a positive point charge at that point in the field

Equation for acceleration of a charged particle in an E field

Efs x Specific charge

Equation for acceleration of a charged particle between parallel plates

a= Vq/md (V= voltage)

What Suvat do you use for horizontal deflection of a charged particle

S= ½at²

How do you find the resultant efs?

minus the field strengths but for radial you half the lengths and for uniform you keep the lengths

What are the electric fields strengths of circuits?

Always uniform
