Definitions- Static Electricity

Question 1

Coulomb’s law

Answer 1

Two point charges in free space or air exert forced in each other. The force is directly proportional to the product of the charges and inversely proportional to the square of the distance between the charges

Question 2

Electric field

Answer 2

A region of space in which an electric charge experiences a force. The direction of the electric field at a point is the direction that a positive test charge would move if placed at that point.

Question 3

Magnitude of an electric field at a point

Answer 3

Force per unit positive charge
