Summary ELECTRIC CHARGES AND FIELDS

Physics - Electric Charges and Fields
Newton's Law of Coulomb

 States that the force between two charged particles is directly
proportional to the product of their charges and inversely
proportional to the square of the distance between them

Types of Charges

 Positive and negative charges
 Conservation of charges

Electric Dipole

 Vector quantity representing electrical polarity and charge
distribution

Electric Field (Dipole)

 Evaluation of electric field due to a point dipole, which
involves calculating net electric field at axial and equatorial
points

Equatorial Point

 Region on the perpendicular bisector of the separation vector
of a dipole, where the electric field is greatest

Electric Field of an Infinitely Long Wire

 The electric field due to a uniformly charged infinite wire has
an inverse square dependence on the radial distance
