Electric Fields

Question 1

Coulomb’s Law

Answer 1

Coulomb’s law states that the force between two point charges is proportional to the product of the charges and inversely proportional to the square of the distance between them

Question 2

Electric Field

Answer 2

An electric field is a region of space in which a charge placed in that region experiences an electric force

Question 3

Electric Field Strength

Answer 3

The electric field strength at a point is defined as the electric force exerted per unit positive charge placed at that point

Question 4

Electric Potential

Answer 4

The electric potential at a point in an electric field is defined as the work done per unit positive charge by an external force in bringing a small test charge from infinity to that point

Question 5

Electric Potential Energy

Answer 5

The electric potential energy of a charge at a point in an electric field is defined as the work done by an external force in bringing the charge from infinity to that point
