Chapter 13 Electric Field

Question 1

Coulomb’s law

Answer 1

Magnitude of electric force between two point charges is proportional to their charges and inversely proportional to the square of separation

F = Qq/(4πε₀r^2)
ε₀: 8.85×10^-12 Fm^-1

Question 2

Electric field

Answer 2

Is a region of space in which a charge placed in that region experiences a force

Question 3

Electric field strength

Answer 3

Electric force exerted per unit positive charge acting on a test charge placed the point

E = F/q

Question 4

Electric potential energy

Answer 4

Work done by an external agent in bringing the charge from infinity to that point

Question 5

Electric potential

Answer 5

Work done per unit positive charge in bringing a small test charge from infinity to that point by an external agent
