Electrostatics

Question 1

Elementary charge unit

Answer 1

The quantity of charge on a proton or electron

Question 2

Total charge

Answer 2

The sum of all positive and negative charges in a piece of matter

Question 3

Principal of conservation of charge

Answer 3

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

Question 4

Triboelectric series

Answer 4

List of different materials, based on their ability to become positively charged

Question 5

Coulomb’s law

Answer 5

Every charged object exerts a force on every other charged object.
The magnitude of the force is directly proportional to the product of the charges and inversely proportional to the square of the distance between the charges

Question 6

Point charge

Answer 6

The charges do not have any mass or occupy any volume themselves, they only contain charge

Question 7

Electric field

Answer 7

Region of space in which an electric charge experiences an electrostatic force.

Question 8

Direction of the electric field

Answer 8

The direction of the force experienced by a small, positive test charge

Question 9

Electric field magnitude

Answer 9

The force experiences by a small, positive test charge per unit test charge.

Question 10

Charge

Answer 10

An inert property of matter that creates force
