ELECTRIC FIELD
The area or field around a charge where the electrostatic force can be experienced
ELECTRIC DIPOLE
(two opposite charges with equal magnitude)
E
electric field
Q
source charge
r
distance from the source charge
k
Coulomb's constant
Fe
electrostatic force
q
electric charge
E = F/q = kQ/r^2
