Uniform electric fields

Question 1

Electric charge

Answer 1

a property of an object that gives rise to a force on the body when the body is an electric field

Question 2

Electric field

Answer 2

a region where a charged object experiences a force

Question 3

Field of a force

Answer 3

a region of space where an object feels a force; the force may be gravitational, electric, magnetic and so on

Question 4

Field lines

Answer 4

lines drawn to represent the strength and direction of a field of force

Question 5

Electric field strength at a point

Answer 5

E = F / Q
electric field strength = force on charge / charge

the force per unit charge exerted on a stationary positive charge at that point

Question 6

Strength of a uniform field between 2 parallel metal plates

Answer 6

E = ∆V / ∆d

electric field strength = change in potential difference / change in distance
