5.3 Electric Fields

Question 1

EFS

Answer 1

Electric field strength, E, at a point is the force experienced per unit positive charge at that point

Question 2

Electric field strength equation

Answer 2

E=F/Q

Question 3

Electric field definition

Answer 3

A region of space in which a charged particle will experience a force

Question 4

Coulomb’s law

Answer 4

Between every two point charges exists an electrical force which is directly proportional to the charge of each and inversely proportional to the square of their separation

Question 5

K value

Answer 5

8.98x10^9

Question 6

Force equation

Answer 6

F=k.Q.q/r^2

Question 7

Uniform electric field strengh equation

Answer 7

E=V/D

Question 8

Similarities and differences between GFS and EFS

Answer 8

Similarities: both obey inverse square law
both have infinite range
Differences: electric field strength can be both attractive and repulsive
Electric field can be shielded
