Electric Fields

Question 1

Coulomb’s law

Answer 1

Two point charges in free space or air exert forces on 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

Electrical field

Answer 2

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

Question 3

Electric field strength

Answer 3
