Electrostatics

Question 1

Principle of charge quantization

Answer 1

All charges in the universe consist of an integer multiple of the charge of one electron

Question 2

Principle of conservation of charge

Answer 2

The net charge of an isolated system remains constant during any physical process

Question 3

Polarisation of charges

Answer 3

The partial or complete polar separation of positive and negative electric charge in a system

Question 4

What is Coulomb’s law

Answer 4

The magnitude of the electrostatic force of attraction or repulsion exerted by one point charge (Q1) on another point charge (Q2) is directly proportional to the product of the magnitudes of the charges and inversely proportional to the square of the distance (r) between their centres.

Question 5

What is an Electric Field

Answer 5

Region of space in which an electric charge experiences a force

Question 6

What is an Electric Field at a point

Answer 6

The electrostatic force experienced per unit positive point charge placed at that point
