Chapter 16. Charge and Field:

Electric Fields
All charged objects have a field around them. Any charged object within this field will be
either attracted or repelled depending on the charges of the 2 objects.
You can work out the force acting upon the objects using Coulomb's Law ,…

Electrical Potential
Electrical potential (V) is the amount of electrical potential energy for each unit of charge.
E kQ
V elec = elec = . Electrical potential (V) is measured in Volts.
q r

Uniform Fields
A uniform field, is different to a radial field as, the field strength, is…

Charged Particles in a Magnetic Field
Current in a wire is the flow of charged electrons, which, like any charged particles, are
effected by a magnetic field. Current (I) is the amount of charge passing through a wire,
per second. I = .
Previously we derived, F =…

As shown above, a 5MeV particle would, without relativity, go faster than the speed of
light. To take relativity into account we use Einstein's definitions for momentum and kinetic
energy. Firstly momentum, p = m . However, if instead we consider wristwatch time, ,
the time…
