1
Q
State Coulomb’s Law.
A
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 their distance of separation.
2
Q
Define electric field strength.
A
Force per unit positive charge acting on a point charge in an electric field.
3
Q
Define electric potential.
A
Work done per unit positive charge in bringing a small test (point) charge from infinity to a point in an electric field.
