Electrostatics

Question 1

Coulomb’s law

Answer 1

the magnitude of the electrostatic force exerted by one point charge on another point charge is directly proportional to the magnitude of the charges and inversely proportional to the square of the distance between them

Question 2

Electric field

Answer 2

Region of space where an electric charge experiences and force. The direction of an electric field at a point is the direction that a positive test charge would move at that point.

Question 3

Electric field at a point

Answer 3

Electrostatic force experienced per unit positive charge placed at that point
