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

Electric 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 that point.
