Coloumb law Flashcards
define electrostatics
branch of physics and chemistry that studies interactions of non-moving charges and their effects in terms of forces and fields
define electrodynamics
electrostatics concepts but studying charged particles in motionunder acceleration
application of electrostatics
preliminary study of proton/electron interaction
equilibrium positions of atoms within solids
inorganic chemistry
conduction properties of materials within solids
the unit of charge
coulomb 1 C = 1 A s
charge of a proton
+1.602 x 10^-19
charge of an electron
-1.602 x 10^-19 C
charge of a neutron
no charge
letter for charge of an electron and proton
+ and - e
what is coulombs law
objects with an electrical charge exert an electrostatic force on each other
the two types of electrostatic forces
attractive and repulsive
what is an absolute charge
the charge given without its sign
what is coulombs law equation
ke = modulus q2 x modulus q1 / r^2
assumptions in coulombs law equation modle
the charges are point charges, equivalent ions are the same
ke is constant in each medium
what is the net electrostatic force at equilibrium
0
how can you change the equilibrium position of the ions
introduce an external ion
change the medium
