Electrostatics

Question 1

How can objects be charged

Answer 1

Objects (insulators) can be charged by contact (or rubbing) - tribo electric charging

Question 2

Define Triboelectric charging

Answer 2

A type of contact electrification in which certain materials become electrically charged after they come into contact with different materials and are then separated (such as through rubbing)

Question 4

State the principle of conservation of charge

Answer 4

The net charge of an isolated system remains constant during any physical process. Eg. Two charges making contact and then separating
