coulomb's law
electric fields
electric field strength at a point is the force per unit positive charge that acts on a stationary charge.
E = F/Q
when there is a uniform field between charged parallel plates
field strength = potential difference / separation
-
electric potential
if a +ve charge moved in direction of electric field, its electric potential will decrease
and vice versa
if charge accelerates in the field, its electric potential energy will be converted to kinetic energy
-
coulombs law: any two point charges exert an electrical force on each other that is proportional to the product of their charges and inversely proportional to the square of the distance between them
